AirTalkr is another multiple IM client application immediately available in its beta version for Windows, Linux , Mac OSX as well as on Web-based version.

IM supported protocols are MSN, ICQ, GTalk, Yahoo and AIM but AirTalkr also connects you to your YouTube and Flickr accounts. In addition, AirTalkr creator Hu Shunjie comes with an interesting concept called "AirCards". AirCards are profiling cards where you can add of your buddies information such their Twitter and blog updates, their photos on Flickr as well as their profiles on MySpace and Friendster.

AirTalkr is a very light application but requires the installation of Abobe Integrated Runtime (AIR) which enables developers to use Flash, Flex, Ajax and HTML to create rich interface applications.

The AirTalkr version is still beta and some bugs have been reported but I personaly like this very smooth application and really looking to see what will come next (Skype, more social networking plateforms supported, etc..)

It definitively worth a try. Did I mention that AirTalkr is free and totally Ads-Free (Thanks Hu!).
