Microsoft Community Kitchen: Blogs and RSS come to Microsoft.com. I won’t repost all that I wrote there, but the bottom line is now it is much easier to find blogs by Microsoft employees about the product or technology you’re interested in.
Oh, and that hidden feature I mentioned? How about an OPML blogroll of every registered Microsoft blog, categorized by product? How about one just for SQL Server, or Longhorn, or Xbox? Or Internet Explorer? If there are others you want to see, let me know and I’ll post them.
