Tired of using IM Clients? Well, I can't blame anyone, these stuff suck up more of your computer resources. It could slower their system especially those who still uses later hardware versions. You better try this!

Meebo is a web based IM that lets you log into your IM networks from any computer with a browser and internet connection with no firewall issues. It employs technologies (like AJAX) to make it act more like a desktop application, which dramatically improves usability. Many users enjoy the benefits of a native DHTML application, as it does not consume as many system resources as a Java applet (such as ICQ2Go or Yahoo Web Messenger).

Some users are also experimenting with setting meebo as their Active Desktop page to use meebo like a native Windows application for their instant-messaging purposes.

Meebo is a web messenger for IM services like MSN, GTalk, Yahoo!, ICQ, Jabber & AIM
