I can't say much about much about what took place in an internal debrief around Live.com and Spaces.com. I have to watch my wording here as I could get into trouble for letting things slip, suffice to say I can talk about what's public today.
Live.com exists, it's got a lot of already established goodness on the table and what most of you see via dev.live.com has gotten better, and one day in the near future you'll see more and more additions to this approach taken by Microsoft.
At first when I heard Microsoft was heading into Web 2.0 space with Live.com, I must admit I rolled my eyes and simply "nodded" and smiled. I was an idiot, as once you look at ASP.NET + AJAX Toolkit and then think some more around Web 2.0, you don't have to be smart before you realize that these folks may know a thing or two about empowering users of all walks of life (coders, designers etc) to create their own Web 2.0 pieces.
I urge you all, whom play with the Web 2.0 concepts and AJAX for that matter, to take a look at dev.live.com and download Visual Studio Web Express (Free, as in Beer) with ASP AJAX Toolkit and start learning now.
As from what I just saw in the past three days, I can only give a strong thumbs up.
So far these are some of the pieces available today around Live.com
I also have uploaded some Photos of my AIRLIFT07 Seattle adventures, so if you have time to kill check them out. Also keep http://blogs.msdn.com/klevy/ blog in your RSS watch list as he has the inside scoop around what MIX07 will have in stock.
