InstantBird -- Instant Messenger Communication Tool from the house of FireFox

I was casually browsing http://www.mozilla.org/ and I found out an innovative product called 'InstantBird'. It seems to be a promising product in that it it is opensource like other products of Mozilla. The main objective of the product is to offer instant messaging support for widest range of networks including Windows Live, Yahoo, AOL, Google Talk and ICQ.

I think it would be a good tool compared to heavier shareware alternatives right?
