IM/Skype-like clients with an added status message logger (side note: ideally OSS client and protocol, p2p (with async message buffer), encrypted).
Every time a user changes his status message it gets logged as if it were a tweet. It's more like facebook than twitter, though, in the sense that only mutual "friendships" would be possible (could be made configurable: "allow anyone to see my status updates, but not my online status, and only allow mutual friends to chat/talk to me").
It would be a pretty good signal to noise ratio for most people.
