On Reddit people are constantly trying to maintain a string of popularity and by doing that you write to the LCD, on 4chan you write whatever you want, and if it's actually good you'll get your (you) but if it isn't you don't go back and apologize, you say "Fuck all of you faggots" and stop posting that way.
Oh, and Reddit has the worst UI I've ever fucking used in my life, even if I wanted to use it I couldn't.
