This is through IE8 on XP SP3. All links in the feed ("headline" links and "comments" links) all point to http://channel9.msdn.com/forums/rss
Oh wait, now IE tells me "This feed contains errors. Internet Explorer will try updating this feed again later."
edit: okay the IE error went away but the links are still wrong.
I 'll try deleting cache/cookies.
edit2: nope, clearing cache/cookies didn't help. Is anyone else experiencing this?
