Google's long history of acquisition, innovation, experimentation, successes and failures is dotted with household names (YouTube) and forgotten brands (Jaiku anyone?).

The following Infographic from Mashable puts Google's Social Media history into the contect of a timeline. I for one, refuse to get excited by the prospect of Google launching it's Facebook competitor Google Me particularly as I've often thrown the full weight of my enthusiasm behind the likes of Orkut, GoogleWave, SideWiki and Aardvark only to be bitterly disappointed.

Anyhooooo....
