It's been quiet here for a couple months, but plenty of things have been happening in the RSS world. Most recently, Windows Live Spaces had an update (more at the Space Craft blog).
Mike Torres, all-powerful lead PM on the Spaces team dropped me note to point out that they went RSS-crazy in this update, with category feeds, feeds for every list (even a feed for all lists), profile feeds, comment feeds, a feed of your friends, and even a feed of all of the feeds on your space.
It's fantastic -- everything you might want to get is accessible via RSS!
Mike's blog post has all the details.
