As Josh Ledgard and Brian Johnson have noted, the upgrade of blogs.msdn.com to Community Server 1.0 changed the URL format for all of our category feeds. If you were subscribed to any of my individual categories, those feeds are now failing with no redirects in place. Sorry :-(

Changing feeds with no redirection is probably one of the cardinal sins of blogging, and definitely wasn't supposed to happen. It's also the reason why you might not have seen any recent syndicated blog posts on the various microsoft.com community sites (since no-one told the blog registration tool about the new URL format either). Hopefully redirects will be in place tomorrow. Normal service will be resumed as soon as possible…
