Instant Messengers

I absolutely don't like all the messenger clients hogging up system resources and precious taskbar area. The alternative till now was to use a multi-sign-in IM client like trillian, gaim or jabbers. I've also heard friends working in other organizations complain about these IM clients disabled in their network. Well, not anymore I guess. Check out the browser-based meebo, brining IM to Web 2.0. Ofcourse, it doesn't have all the additional features like sounds, emoticons, webcam sharing, etc, but good enough for one-on-one text chat. Also, recently launched is gtalk on gmail.
