I've always been fascinated by forum up/down voting patterns. It's a lens onto human group behaviour.
I've said things that are totally wrong and been voted up, and said things that are essentially correct except for some tiny detail and been voted down into oblivion.
What especially gets people riled up is if there's an element of tribalism involved. Can be anything: text editors, political party, operating system, programming language, or whatever. You don't even have to be pro/anti any specific tribe. Just mentioning anything to do with such a topic gets people worked up and angry even if your point is strictly neutral or objective.
It's always fun to watch this play out in the microcosm of some obscure topic...
