Meebo

I was doing some research into AJAX srcipting to write webpages and I found a list of sites that were known to use AJAX.

One of them was Meebo, which is very simple but excellent. It lets you use all your IM clients from the webpage (Yahoo, AIM, ICQ, Jabber, GTalk & MSN).

I was a bit unsure about typing my password in but gave it a shot and was very impressed.
