Facebook vs. Reddit

I have noticed that on facebook, who cares how you spell. On reddit, one spelling mistake and you get comments beating the shit out of you. Most of us people and aliens of all on reddit hate facebook, yet when there is a screen shot from facebook everyone upvotes it because the one person on facebook from reddit tells them off. If its good enough to upvote because smart people on facebook is rare, why don't we all just storm facebook and suddenly the average IQ of the people on facebook will skyrocket, less spelling errors will occur, and it will be a better site.
