A bunch of RSS news relating Longhorn news will start emerging:

Robert Scoble:

"I just posted the hour-long interview I had with Microsoft's Longhorn Browsing and RSS team. More shortly after the announcements get made."

I'm going to update this post with any Longhorn RSS I find today.

Update:

BetaNews:

"Microsoft has developed an Application Programming Interface (API) for Longhorn that will perform the baseline tasks associated with RSS for developers. Because of this, no additional programming will be required to provide the ability to subscribe to and view feeds from within applications.

...Microsoft will deliver any modifications that it makes to the RSS standard to Creative Commons licensed under the Share Alike attribution agreement."

Geek News Central:

"Microsoft is saying they are betting big on RSS in Longhorn and IE 7

1st Throughout Windows RSS enabled
2nd provide a RSS platform that will help expand RSS
3rd Cover more scenarios

Internet Explorer version 7 automatically detects rss and shows a view that people can see the feed in a readable format and it integrates directly with RSS aggregators. They are creating an my feed directory like you have my pictures which will contain all of your feeds that will integrate with all RSS Aggreators."

ZDNet:

"The software maker said on Friday that it will build support for RSS into the next version of Internet Explorer, as well as into Longhorn, the Windows update scheduled to arrive next year.

"We really think that RSS is going to be key to how people use the Internet in the future," said Gary Schare, a director of strategic product management for Microsoft's Windows unit. "Because of that we are betting really big on RSS in Longhorn by integrating RSS throughout the operating system." "

Update II

AP:

"Microsoft also said it will provide simple list extensions to enable Web sites to publish lists as RSS feeds, such as photo albums, music playlists and top 10 lists."

Reuters:

"Hachamovitch is set to embrace the Creative Commons license backed by many leading RSS supporters. The license provides looser copyright restrictions on creative work but stops short of entirely giving up all claims of ownership.

"That's groundbreaking for Microsoft," Joe Wilcox, an analyst at Jupiter Research, said of the software giant's embrace of Creative Commons, which has served as a rallying point for computer users opposed to Microsoft's industry dominance."

Steve Rubel:

"My initial take is that by embracing RSS in Longhorn and supporting "developers, developers, developers," (as it usually does) Microsoft will evangelize the platform in a way that no one else can. No one else is in the same position to bring RSS to the mases the way Microsoft is - and they will!

However, Microsoft needs to be very careful not to push the technology too far so that it only benefits them. It will be interesting to see if the extensions they are planning to add to RSS are truly open to everyone on all platforms (e.g. Linux and Mac) - not just Windows. Otherwise, it could be a repeat of embrace and extend - which got Microsoft into a bit of trouble back in the heyday of the browser wars. "

Update III

Microsoft Monitor - Microsoft’s RSS Platform: The What:

"While Microsoft’s moves will likely give more legitimacy to RSS and perhaps extend RSS capabilities, I am not convinced that any company needs to create a development platform to get there. My report, "Microsoft 2005: Uncovering Partner and Competitor Opportunities," explains how Microsoft is increasing the number of development platforms and using integrations to drive sales of saturated core products, Office and Windows. The RSS platform is merely an extension of that approach."

Microsoft Monitor - Microsoft’s RSS Platform: The How:

"The potential content possibilities are astounding. Right now, RSS isn’t much of a commercial opportunity. Worse, it poses some problems for content providers; many do not distribute full content by RSS because of potentially lost advertising and paid search revenue. Microsoft’s platform approach could enable ways of enabling commerce via RSS. In the previous post, I mentioned Netflix feeds. Another could be specialized Amazon feeds or extended existing links. For example, blogging service TypePad pulls up Amazon links for music and book lists on personal blogsites. Microsoft could further extend RSS with additional tags that could break up content on a single site into multiple feeds, making it possible for someone to read a post and sample stream the poster’s favorite songs.

As long as Microsoft makes future tags available under a Creative Commons license, and that license is really as good as it appears right now, some benefits would be available beyond just Windows. For now, I’ll commend the Creative Commons licensing, which is groundbreaking for Microsoft. Appears to be that Microsoft is really trying to this right, which is highly commendable. But the devil is in the details, and I’m not yet privy to them all."

Kevin O'Keefe:

"At noon today there will be more information on the Microsft site on Microsoft's championing the use of RSS through its operating systems and applications. There will also more info in the weeks and months coming on Microsoft's RSS work at the Microsoft Internet Explorer Development Blog."

Update IV

InfoWorld:

"Some industry observers were encouraged not only by Microsoft's endorsement of the technology, but also because the software giant appears uninterested in dominating the technology and is being proactive in trying to help create commercial opportunities for other application developers."

Microsoft Monitor -Microsoft’s RSS Platform: The Why:

"My prediction: Microsoft will add RSS capabilities to more products than just Windows, just as it did with browsing technology. I wouldn't be shocked to see some tight integration between MSN Spaces and Longhorn via the new RSS platform. And why not MSN Music Store?"

Information Week:

 "A test version of Longhorn--the desktop operating system due late next year--that Microsoft plans to distribute at its Professional Developers Conference in September will include the ability to subscribe to news feeds, blog entries, and other Web content published via RSS from within the Windows user interface. The feature will require the upcoming version 7 of Microsoft's Internet Explorer Web browser, due in test form this summer. Longhorn will also be able to store data from RSS feeds in a central place on a PC's hard drive and make it available to apps such as PC calendars. "We're making a really big RSS investment in Longhorn," says Gary Schare, Windows product-management director. "We think RSS will work better than past push technology."

Update V

MSDN - Understanding RSS in Longhorn

Lawrence Lessig:

"This isn't the first Microsoft site licensed under a Creative Commons license. There's a very cool PatternShare site that builds on Microsoft research licensed under a Creative Commons Attribution license. But this is the first under a ShareAlike license. That's right - the "copyleft" "ShareAlike" license. People are free to modify and redistribute the spec so long as the modifications are licensed under a similar license.

These steps signal important flexibility and sophistication within Microsoft. For anyone who knows people at that place, this is old news. But even if old news, very very good news."

Dean Hachamovitch, IE blog:  

"Earlier today, I went to downtown Seattle to Gnomedex 5.0, and stood up in front of 300 tech influentials, enthusiasts and leaders to talk about some really exciting things that we’ve been working on for the past several months.

The main thing I talked about is the deep platform support for RSS that we’re building into the next version of Windows codenamed “Windows Longhorn.” 

We think that the RSS functionality in Longhorn will make it easy for users to discover, view and subscribe to RSS feeds, as well as make it simple for developers to incorporate the rich capabilities of RSS into their applications."

SiliconValley.com:

"Having RSS built into Longhorn could pose a serious threat to companies that sell RSS readers that siphon data from the Internet. But Kidd contends that Microsoft isn't out to put anyone out of business.

``This is not a replacement for readers by any means,'' she said. ``What this does is enable more developers to create more readers.''

Kidd said Microsoft has done a lot of the ``heavy lifting'' so software developers can focus on creating useful applications for RSS rather than the ``baseline plumping'' of the feeds themselves. For example, Microsoft is hoping developers will come up with handy programs like ones that will send a user's favorite band's tour schedule straight into a desktop calendar, or let a user know when a favorite movie comes out on video."

Mobile Phone Fan:

"So IE 7 will be released soon and it will support RSS. However still no support for enclosures and podcasting and no extensions of Windows Media player.

Of course full RSS APIs and downloading in background of enclosures will be available in Longhorn (successor to Windows XP) but it is 1-2 years in future.

So generally no big deal, but thanks to bloated coverage in blogosphere it looks like big deal."

Sean O'Connor:

"My key takeaway from Dean's keynote is that Microsoft is fully onboard to integrate RSS into Longhorn. To put it simply, their goal is that all feeds will be available to all applications (IE, Outlook, photo browsers, etc). The way I understand it, Longhorn will feature a "clipboard" of sorts making all these feeds available to any application. There are some rather intriguing possibilities for users."

Frank La Vigne:

"Forbes and BusinessWeek are reporting that Longhorn will natively support RSS.

Honestly, I would be surprised if it didn't support RSS or ATOM at the OS level.  RSS (et. al) is the “new HTML” and it's a natural course to see support it integrating into the OS just as HTML was in previous versions of Windows.

And just as in the late 90's when the browser became part of the OS, some people are not happy about the situation.  Player-haters are as prevalent today as they were back in the day."

Eric Freeman, O'Reilly.com

"If you're scratching your hand thinking "so what? I can do all this on my Mac now," you'd be in sync with most of the audience. That said, there is a bit more to the story: what Microsoft has done is essentially build an RSS aggregator into the OS and expose API's that any application can make use of to produce or consume RSS. That's a little more interesting (and perhaps would have made for a more interesting talk and discussion)."

Kevin Briody, blogging from Gnomedex:

"I actually don’t like how Dean is using a demo guy. A GM in charge of IE should be able to demo IE7 to a small group. IMO of course...

You can tell this crowd is seething with skeptics...

Cool - rss feeds embedded in MSN Search (I think). Talking about an “RSS platform” in LH....

...Steve Rubel just called all this “embrace and extend lite”. Ouch. “Give me evidence that the Death Star is gone and has exploded, and that we are living under Jedi rule.” There is palpable concern in this audience about MSFT - how genuine are they being? Is this another play to force the whole world to adapt to their “standards?"

Niall Kennedy, also provides pics from Gnomedex:

"Dean demonstrated Internet Explorer 7 and its built-in feed reader. Internet Explorer 7 includes an RSS button in the navigation bar when it discovers feed content in the HTML. A user clicks on the orange RSS and is able to view the RSS feed rendered in the browser. Clicking a plus button adds the feed to a common feed list Microsoft has opened up to developers as CommonFeedList. CommonFeedList provides support for feed elements at the platform level and opens up different API calls to store and retrieve feed data from the OS."

CIE Thoughts:

"Blogs across the world are covering the news that Microsoft is joining Apple, Yahoo!, the BBC and others, and going to town with RSS in Longhorn, the next version of Windows. As Lawrence Lessig (and others) points out, they've released the definition of their extensions under a Creative Commons licence. I wonder if they'd like to read our study? "

Chris Heuer:

"Bob Wyman held Dean's feet to the fire concerning Microsoft about how come they are ignoring existing standards bodies to put themselves at the point of origin for the next wave of stuff. His answer was really not very good - though he did use humor to defuse the serious nature. Bob is right, particularly in light of the fact that MS has this new standard and licensing format but did not have a community process figured out. On the spot, Scoble offered up a WIKI - shows that he really is one of the smartest people at Microsoft."

Update VI

Tim Bray:

"Hey, I see Microsoft announced RSS Support in Longhorn; good stuff! The services they plan to provide (subscription list, data store, sync engine) sound pretty plausible. As for their list-control extensions, it’s up to the implementors and the market to decide if they’re useful; they look like they won’t break anything, so the experiment is free."

BBC News:

"IE7 will have an orange button on the toolbar which will light up when it detects a Really Simple Syndication (RSS) feed on a site...Users can click on a "plus" button to subscribe to the site's feed, as they would with a bookmark.

... "We are making sure that throughout Windows the experiences for users are easy," said Dean Hachomovitch, general manager of Microsoft's Internet Explorer team.

 "We want RSS everywhere. I want it in more than just the browser and aggregators. We want to help RSS get even bigger and better than today.""

David Berlind, Between the Lines:

"Many who are reading this news for the first time will begin to think that history is repeating itself.  I'm talking about the history where Microsoft embraces some standard and extends it.  Microsoft has announced that it will, according to Kidd, "make the Simple List extension specification freely available under the Creative Commons Share-Alike Attribution Deed" (the commercial version, not the non-commercial version).  As such, this represents yet another type of license that Microsoft is applying to its technologies. This extends the range of specific licenses — from proprietary to full-blown open source — that it already attaches to it's existing technologies.  Did Microsoft just catapult itself from open source laggard to cutting edge licensor?  Whatever it did, this is definitely not the Microsoft the world is used to seeing (granted, if thousands or millions of publishers make use of the specification, it could drive demand for the Microsoft operating systems and applications that support it)."

Update VII

Wesner Moise:

"Also introduced were Simple List Extensions, which enable ordered lists (Simple List Extensions), enclosures for any kind of content, and additional fields for sorting and filtering. These extensions use the Creative Commons “share-alike with attribution” license.

This new platform gives Windows a new and versatile notification mechanism, already being used widely on the Internet, but now also open to interapplication communication on a local machine. In the latter case, the operating system or an application might be able to create feeds through the new RSS APIs that can be read by other applications. With the APIs, the data may actually be transmitted natively (or dynamically constructed) with no RSS generated in between except when communicating with a remote computer."

John Bell:

"One of the features, is a common feed list. This is something that I've noticed using Safari and Radio at the same time. I have to find, subscribe and read the feeds twice. There's no understanding between applications of what I've subscribed to and read. Being able to syncronize across applications for feeds is a great idea. This is something that I've also been thinking about in relation to tools like DevonThink and such, that there's a core mechanism of storing objects which should be a store shared across the entire system. Similar to the way that the addressbook becomes usable at the core of other applications, and extendable in contact manager tools. In some ways, spotlight becomes the UI for this, and the filesystem becomes the store, but until there's a real object DB basis for the file system, this won't become a true feature. I'm starting to see how this is a huge feature, which is described in the Ars Technica articles about Tiger and Spotlight.

 The way that spotlight handles documents, in understanding how to handle and pass to a viewer, is an example of how the RSS enclosures would be handled from the core API."

Matt at Gnomedex:

 "Microsoft gave these out after the Longhorn RSS announcement"

MS Longhorn Jacket

Chris Heuer (again):

"One of the great things MS does is how they leverage their developer and beta community to provide them with up to what some estimate to be be an extra $3-4 billion of research and development. They are smartly doing this again, but this time they are presenting it in a more inclusive tone. Judge as ye will, but the spirit of their requests for community involvement seems to be coming from the heart - or at the very least, coming from the hearts of the individual's representing the corporation."

Slashdot comment:

" 1. Pick an up and coming technology that _you_ didn't see coming (and that your products don't support at all).

2. Point out a fault in it. Promise to *fix* it by changing the standard so the improved version is only compatible with your software.

3. Get people to believe the technology isn't ready until you have a chance to support it.

4. Sell it as a new idea and profit.

Look, I made an ordered list without extending /.
"

Jame Healy:

"It would seem that Microsoft is starting to embrace RSS. This support is to come in the Longhorn timeframe and not without skeptics weighing in. I agree with Scoble, that the concept of extending RSS is not necessarily blasphemous."

SearchViews:

 "RSS guru Dave Winer says he's pleased, (in his own grouchy little way) and others in the community are as well.

Microsoft-Watch.com has excellent coverage.

This is a great move for Microsoft, and its good to see a major corporation listening to those in the community for once. Speaking of RSS (and Microsoft), check out their huge index of product feeds featuring everything from Microsoft Flight Simulator to MSN Messenger. IT managers and DIY'ers take note."

Dejee:

 "One question: how soon before the open-source community builds a general aggregator engine?"

Steve Richards:

"I have been writing about RSS for about a year now and my vision for RSS is highly congruent with Microsoft’s.  However I have only learned that this is true today, as I have seen Microsoft’s RSS strategy unfold.  Whilst I am not surprised by the announcement I am relieved as I truly believe that making RSS a subscription protocol that supports many different application types will revolutionise the way we work, and make all of our lives just so much easier."

Update VIII (still Friday)

Dare Obasanjo (Microsoft):

"Using XML syndication is an evolution in the way people interact with content on the web. The first phase was browsing the Web for content using a web browser. Then came searching the Web for content using search engines. And now we have subscribing content using aggregators. Each step hasn't replaced the latter but instead has enhanced user experience while using the Web.  In Longhorn, Microsoft is betting big on RSS both for end users and for developers in three key ways

  1. Throughout Windows various experiences will be RSS-enabled and will be easy for end users to consume
  2. An RSS platform will be provided that makes it easy for developers to RSS-enable various scenarios and applications
  3. Increasing the number of scenarios that RSS handles by proposing extensions "

Richard MacManus:

"I'm continuing to absorb this news. My initial impression is that this is indeed very big - possibly even Microsoft acknowledging that RSS is to Web 2.0 what HTML was to the Web in the 90's. Which is to say, this is Microsoft embracing and extending RSS like they did with HTML 10 years ago. I'll leave the question open, for now, as to whether they'll be as ruthless in this strategy as they were in Web 1.0."

Indexed Forever:

"My guess on the announcement – Longhorn needs a value proposition beyond a faster UI for people to upgrade. And RSS is a great value proposition. Prepare to be saturated with Longhorn advertising stressing RSS benefits next summer. It started today with their positioning on the evolution of Windows – Browse, Search, Subscribe!"

Steve Rubel (again)

 "This AP Photo says a lot. It's a picture of Dean Machamovitch's sneaker taken today at Gnomedex. He's Microsoft Corp. general manager of Longhorn browsing and RSS technologies."

Heather (Like No One is Watching):

"Don't know what RSS is, you will in the near future if Microsoft has anything to say about it. Alex Barnett, a Microsoft employee, has a nice post on his blog that explains RSS and he even has a short screen-cast that shows you how to use FeedDemon, a popular news aggragator for PC users. This is exciting stuff."
