It's so stupid, it's for nosy people who spend 20 hours a day watching other people's pictures/videos and commenting on them. It's so gay !
Nevertheless, if you have any stupid idea (like the 2012 shit) that you want to spread it across 100 000 human's mind in less than 3 days, share it on facebook. And considering the great number of dumb people out there, you're more likely to succeed. There is no point in having an account there. It's good for gov to know how their population is doing "mentally" at least, through their interests and discussions and shits given by facebook admins or whoever the fuck they are haha !
