Nick Bradbury: So I have to point out that the feed:// protocol (aka: feed URI scheme) was created to resolve this problem. Is it a perfect solution? No, it's not (there's no such thing). Past discussions about this idea have devolved into arguments about MIME types, but I maintain that it's the best one we've got because it works right now.
Randy: I have to disagree. It doesn't work right now. Take a look at my right sidebar. It's full of chicklets. Nothing there works right now. Adding feed:// will only confuse the user. He'll click on it and his browser will barf.
