Basicly newgrounds sucks. Too many furious, full of angst idiots that aren't funny (I'm sometimes one of them). Just crying around...
Anyway, the reason (in my opinion) why people get addicted to newbgrounds is THIS: They see popular people (mods, Willi, Mecha, etc...) and other regulars. They don't want to be other regulars, so they try their best to become popular here. And their greediness kills them (not literally).
Bottom line, when you're going to quit this website, you'll regret on how many hours you've spent on newgrounds. But after some time you'll get over it (probably) and laugh every time you hear the word "Newgrounds".
Just pointing out the obvious.
