MSN Launches Web Version Of Messenger

You can now access MSN Messenger via the web, just like with AIM Express. It supports IE 5.0, Netscape 7.1, Mozilla and 1.6 (or better versions). One cool feature is that it lets you choose your online status before you log on (in case you want to be invisible from annoying people).

Also, if you care, MS released a preview of its Avalon display system for Longhorn.
