It looks like a small and mostly trusted community for the time being. The problem of course is always scale which is a problem mostly based on the need for revenue. Maybe this doesn't need revenue. Wikipedia gets by on donations.
I have actually just started using Twitter again. I was a light lurker, but stopped all social sites except The Core in 2015. I've since added back Strava at the behest of a friend and have recently started using Twitter (in lurker mode) to follow a handful of fitness people and two writers. If you have a very small number of people you follow and they are not posting massive amounts, the feed is fundamentally straight chronology unedited, like the old days. The fact that Elon is losing a huge amount of money on it is just a bonus.
