Xfire

Xfire is a free application that combines multiple gaming tools into one powerful tool to alleviate the need to run multiple different gaming related programs. For instance, Xfire allows you to chat with your friends, see what games they are playing, what servers they are playing on and join them instantly with one click. Xfire also allows you to show off your gaming skills by capturing screenshots and videos and uploading them to your Profile page on the Xfire website.

Yeah xfire is windows only but both plugins work very well so I guess we can leave it(it's the only active server browser yet
