I was looking around my logs again and check what my visitors are searching and found a result about yahoo web based messenger where I have a post located here. Actually they are not just the one offering a web based messenger on the internet there are others. SO to my visitors needs, I will try to list some of them that I know of where you can chat using your browser and no need of downloading a software for it.

http://webmessenger.msn.com/
www.e-messenger.net/
www.meebo.com/
webmessenger.yahoo.com/
www.iloveim.com/
www.msn2go.com
www.communicationtube.net
www.ebuddy.com
www.aim.com

So you see there are other browser based messenger where you can chat or even log-in to different web based messenger on a single site like meebo. MSN has also its web based messenger. Wondering about google? hmn, maybe they will also create one, dont know just maybe.

Enjoy this list and if you know others just comment and I will add it on the list.
