Group chat with chat rooms combining your Facebook Friends and Twitter followers
You can login either via Facebook Connect or Twitter OAuth and then chat away. Your avatar from Facebook or Twitter, depending on your login mode, will show up in the chat window along with a superimposed icon showing an “f” or a “t” denoting which social networking site you’ve come from.
Chat room administrators can control things like duration of the chat, hashtags to use, etc. Chat rooms can be public or private (password protected).
