In order of stupidity, from greatest to least:
Youtube
Gamefaqs
Facebook
4chan
Youtube is a given. Half of the people commenting just want to throw in their own 2cents about the video, which is fine, I enjoyed that funny cat doing that funny thing too. Then you have: the people that post in an attempt to be "that guy" with the highest rated comment because that makes their epeen hard, the people that think arguing in youtube comments means anything, the people saying how much they hate the video and how they'd rather watch goatse (I assume they then open a page to goatse and beat off), and the ones I hate most, the people who will reply to your comment that you posted several years ago, and tell you how much you are wrong... I don't know about you, but I can't remember my opinion of a post I made a year ago... When I get a message from xXthEcoOlgUyXx saying how wrong I am for being an atheist, I first go "what the fuck?" then after spending a few minutes trying to find my message--would it really kill youtube to include your message when someone replies to it? its so hard to find what you said in the first place when there are 10,000 comments >.>--I either reply with "you're an idiot" or just ignore the guy. Worst part is, I KNOW that if I don't respond, they'll be "HA! I WON AN ARGUMENT ON THE INTERNET! I AM SO PROUD OF MYSELF. TIME TO GO BEAT OFF TO GOATSE! YEAHHHHH!!!!"
Gamefaqs is like Escapist except it is only gaming topics, the mods drink turpentine and are blind, and no one has respect for any other person. Thats the best way I can sum it up. Just pretend that everything good about Escapist is gone, and you get Gamefaqs... I still have no idea why my friend uses it all the time... I've tried to convert him over to Escapist many times! =(
The only reason I still use Facebook, is to troll people. There is technically no moderation on Facebook besides IRL moderation, so you can troll the fuck out of people; and ohhhhh how they rage xD
I am still baffled at how 4chan has mods. I have been on some of the boards, and while some of them have some interesting discussions, most of the boards I see on 4chan are rampant unchecked trolling. Then suddenly a mod wakes up, starts banning people, people wait a few minutes, and then resume the flame wars. I really don't understand how 4chan works to this day =|
