I'm constantly baffled by my coding professor suggesting stackoverflow to students for asking questions because of the experience I am seeing others have there. The new ones are always downvoted and the only reply usually just calls the person stupid. I'd just kinda accepted that this was the culture I was going to matriculate into when I graduate.
I still firmly believe one of the worst things to happen to the internet, besides pop-up ads, is up and down votes. Nothing exposes a misanthrope quicker than forcing them to comment instead of passively downvoting everything they see. Which makes it easier to remove them from the party.
