This is why I absolutely LOVED FriendFeed. Not only could you follow arbitrary RSS feeds and FriendFeed users, but you could group feeds into "imaginary users". This was great because you could follow anyone you wanted, even if they didn't use FriendFeed themselves.

So what happened to FriendFeed? Acquired by Facebook and then killed.
