Apparently, Palmer Luckey -- founder of the recently Facebook-acquired Oculus VR and inventor of the Rift -- was a very early Bitcoin adopter and miner. He even claims he lost a lot of money in the MtGox collapse. Both he and John Carmack (and probably others in Oculus) are Bitcoin believers.
Palmer also says he has tens of millions of Dogecoins, and got his first ones three days after launch.

I'm suspecting that Mark Zuckerberg might soon acquire a Bitcoin-related company and integrate some kind of BTC payment services in the Facebook interface.
