My skeptical side is also now reminding me that Zynga used the Facebook platform to establish it's market position. It would be make sense as an overall strategy to p'n'd, as it's easy to create the logical counter-point that "Zynga and Facebook aren't the same thing, duhhh bitcoiners say the stupidest things". Possibly too skeptical, but I'm still a little confused that we've not seen more price movement from what would be a pretty significant PR coup for bitcoin (can't see how it would actually be a big money maker for Facebook, who I understand aren't profitable in a way that doesn't involve a subsidy for allowing access all areas to the NSA)
Bitcoin adoption from the second most well known brand on the internet should generate a bigger price rally, and more secondary reporting of the fact than from just one bitcoin news site.
