It's pretty funny how you imply I'm saying facebook is evil because it makes me feel good - pretty ridiculous statements in light of what I've actually said. I was just saying facebook is a business. It seems you have a lot to prove though. Sorry, I don't buy that "It was solely to see if we could make people feel less self conscious by decreasing social comparison" is the main goal. It seems like a pretty direct way of driving user engagement, seeing as you're literally removing an inhibitor of engagement.
