This worries me, someone who has built the worlds largest repository of more than a billion people's thoughts, photos, address, phone numbers, friends, etc and actually could give two f**cks about user privacy, and was a part of the NSA PRIZM program (naturally) getting into btc will completely throw out what bitcoin is about.

No thanks Mark.

I remember someone mentioning that back in Facebook's early days Zuck was speaking to his cronies, and mentioned that "people who use Facebook are stupid" this was before the platform was opened to devs. Once the open graph and other FB APIs became available and I took a look at the massive amount of data you could use in your app I was a believer in the fact that he probably did make that comment.

Many of the people using Facebook have no idea the things us developers can access on them. Remember Mark is a nerd.
