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.

As we noted last night, Twitter has significantly expanded the rollout of its new “Lists” feature over the past day or so.

The feature looks to accomplish a couple different goals: for one, it lets you organize the people you follow into groups – for example “co-workers,” “social media experts,” or “celebrities” – serving as a filter of sorts for tracking updates. This is similar to the functionality already available in clients like TweetDeck or Seesmic.

The PlayStation 3 might not be winning the console wars, but the system has quietly started to find its niche as an all-in-one home theater media system. Today, the PlayStation Blog announced that Netflix is coming to US-based PlayStation 3’s next month.

The PlayStation 3 will join an ever-increasing number of devices that support Netflix Watch Instantly streaming. Last year, Microsoft and Netflix announced a partnership that brought Netflix support to the X-Box 360.
