Jake Jarvis of Ridge High School has brought Meebo to Facebook. Thanks to this application you can allow your profile visitors to chat directly with you. If you are not logged into your Meebo account, the application will leave a message. While there are already live chat alternatives, including one that I profiled earlier, this one is the only instant messaging application that I know of. So if you want to add chat capabilities to your profile, go check out the Meebo application.
