Why couldn't Facebook let FriendFeed live? The numbers may be down, but Facebook makes frigging millions, and a few bucks on server space for FriendFeed can't surely be a huge drain?
It was inevitable that once Facebook got their grubby paws on FriendFeed that it would eventually pull the plug. Heck, FriendFeed doesn't mine all your personal data, and serve you myriads of annoying brain dead advertising like Facebook does!
