He announced his surprise change of job on micro-blogging platform Twitter, posting: "Now that Chrome OS & WebGL are in good shape, it's time for something new. I'm going to work @ Facebook! Love the product and team. Woot!"
According to his online resumé, Papakipos has filed over 70 patent applications with the US patent authority and has degrees from Brown and Stanford Universities.
