Digsby is a multiprotocol IM client that lets you chat with all your friends on AIM, MSN, Yahoo, ICQ, Google Talk, Facebook Chat and Jabber with a simple to manage buddy list. It supports multiple conversations with tabbed conversation windows. If one of your friends has more than one IM account you can combine them into a single merged contact to eliminate duplicate buddies.
