We’ve already covered how viral the chat options on live video services like Ustream, Justin.tv, and Tinychat can be.
By signing into these services with your Twitter, Facebook, or MySpace credentials and then having your messages broadcast as status updates, more users become aware of the video feed and its audience can grow exponentially.
Ustream just taken this concept to another level by launching what it calls Social Stream. The new feature allows you to sign-in to all three networks simultaneously, plus AIM, and have each chat message distributed to all of them. Further, the chat room will contain messages streaming in from all four platforms.
