Meebo is a web-based instant messaging tool I’ve been playing around with for a couple of weeks now. It uses AJAX technology to display a buddy list and IM windows, and the GAIM library to provide connectivity to various IM services. You can log in to AIM, ICQ, MSN Messenger, Jabber, Google Talk, and Yahoo Messenger. The interface is very smooth and simple, and while it’s not as full-featured as a traditional desktop-based IM client such as Adium, it sure packs a wallop for a web application. It’s also a great choice for when you’re on a computer system that doesn’t have an IM client already, and for whatever reason you can’t download one. The Meebo team is hard at work on pushing out bug fixes and feature releases, and they deserve commendation. Their most recent release includes the ability to set away messages, and the ability to view a buddy’s info and away message while hovering over their icon.
