Meebo
Meebo is a useful site that allows you to stay logged in to your Yahoo!, AIM, Google Talk, MSN, ICQ and jabber accounts. Yes! Just go to Meebo, enter the usernames and passwords of the networks you want to log in to, and you can, without downloading any of the required software. It shows all your friends in a handy buddy list.
IM everywhere? Yes. That’s the great thing about Meebo. As long as you have a browser, and a computer,(an internet connection too, of course :-)) you can log in.
Meebo also has a Meebo Me widget, for webmasters. It just adds a widget to your website or blog, through which your visitors can chat with you. They don’t require an account of their own or anything. By logging in to your account, you can chat with them too!
And oh, to the people who are concerned about security and privacy, the Meebo blog has a post about security of Meebo
In short, I love meebo!

[…] oh, I also added a Meebo me widget. Forgot meebo? Read my entry about it here. Now you can chat with me. Just use the tool on the sidebar. […]
seems like a good idea, i use to use something like this for my psp, however the site went down…and even when it was up the server was always full, im going to try this out. thanks!
