Wow. Thanks to Scoble I just discovered that the Microsoft Knowledge Base now has RSS feeds, organized by category. This is huge news for people like me, who follow Microsoft products for a living and need fast access to new information.
There’s a good RSS tutorial, too, with a list of Windows-based stand-alone feed readers at the bottom. Suggestion to Microsoft: You should add Web-based aggregators to this list.

No fair, where’s the DOS 6.x feed?! What a great resource, thanks for posting.
Hi Ed,
Do you think we should do RSS feeds for book updates?

Sure! Great idea. Why not have an RSS feed for every book that includes teasers of content from the book, as well as updates, corrections, and coming attractions?
