At its core, meebo is a multi-protocol, AJAX-based instant messaging client. It handles all the major IM channels through on a web page. No ad-infested bloat-ware application to load. This month they also added the “Meebo Me” widget which lets you see visitors on your site as chat clients in your Meebo page. This kind of functionality opens up a lot of possibilities – community building, customer support, making things like mySpace more interactive, and so on.
