Good news everybody! We’ve added support for Facebook, MySpace and Twitter and now you can log in through your social media accounts, push status updates about what you’re watching back to these sites!

All channel pages on Justin.tv now include four tabs across the top of the chat window: Chat, Twitter, MySpace and Facebook. In addition to chatting with other Justin.tv users through the Chat tab, users can click on the other tabs at any time to activate the integration features, which are detailed below:

Facebook
After clicking on the Facebook tab at the top of the chat window, users can log in and update their status message about the content they are viewing. Users can then chat with all Facebook users on this channel, or, by clicking the “Friends” tab, they can chat with only their Facebook friends. Chat messages will update in real time, but will not update a user’s Facebook status.

Twitter
After clicking on the Twitter tab at the top of the chat window, users can log in and update their Twitter status about the content they are viewing. By clicking on the “Following” tab, users can filter just the messages from those Twitter users they are following. Hash tags for Justin.tv and the channel will be appended to every Twitter status update. These updates will appear in aggregate on Twitter by going to search.twitter.com and searching for “#jtv or #[channelname].”

MySpace
After clicking on the MySpace tab at the top of the chat window, users will be prompted to sign in and update their MySpace status. Users can then engage in real-time chat with other MySpace users who are viewing the same content. Chat messages will update in real time, but will not update a user’s MySpace status.
