Quick post: That Microsoft was going to be doing something seriousabout syndication was a foregone conclusion. That they'reextending RSS 2.0 to support ordered lists (?) isn't the big news,IMHO. That they're integrating per-user subscription support intotheir forthcoming platform is more significant. They Get It;syndication is a platform, they have a team dedicated to RSS, and thething that's really important to control is personal subscription data.
(The big question is, how long will we be waiting for Longhorn?)
