It's the soapbox syndrome kot. My mutuals and i here were talking it over, what made redditors more willing to stick but not Twitterjaya and we figured, having islands like these instances or communities isn't so different as subs. But also because the social incentives are different. Over there you pose and flex on your soapbox regularly enough you get followers. Over on the more forum setups, you just naikkan the forum's energy, and ppl flock to the forum not the user necessarily. 24/7 rap battle over there, otoh.
