"And what if I'm not a techie but I still want to control my data ?" Then if you were really paranoid about controlling your data - you don't share it, at least not on a publicly accessible network like the internet. It's a simple concept. "And what if I don't want my data to be stored and later used by systems like Facebook Beacon ?" It already is, whether you like it or not, eg, Google.
