I wish I could point you at it, but I was told to keep the site itself under wraps. In short its a social site with friends and avatars and all that other social stuff, that works closely with an extremely cool browser plugin.

I believe it leverages Erlang for the messaging and communications aspect of the plugin, which is of course right up Erlang’s alley. Maybe when it comes out of beta you can interview the folks that are working on it and get the dirty on how Erlang served the project.
