Also the size of the platforms have an effect. If you are on Twitter, even if you mostly interact with people within a select niche, everything is essentially public and anyone can see it or come in and spoil the party so to speak. Twitter / Facebook / itself has a far wider reach than the niche forums or IRC channels of the past, so it is very easy for things to go off the rails with commenters outside of that niche coming in angry about something or changing the conversation etc.. this is largely true on Reddit now as well. The userbase is too broad so it loses that shared sense of community, this leads to misunderstandings, different values, and more arguments. Thus necessitating stricter rules / bans etc.. which can also put a damper on fun.
