Are you chatting via Trillian yet?
I’ve recently checked out Trillian Astra 4 a really smart multi-protocol chat client. It supports most of the popular instant-messaging and social networks including Windows Live Messenger, Yahoo, AIM, Google Talk, Facebook, Twitter, Skype plus of course POP and IMAP email.
The slick interface allows you to chat by text, audio and video so give it a go today! It is currently only available for Windows, web and the iPhone but currently a MAC version is under development.
