Looking back, it's quite surprising how stagnant, in some sense, the social media space has become. How centralised and how... lame.
The big hitters really did pillage and burn. Now, between moderation norms becoming increasingly sensitive and the hard turn the web took away from open... It's hard to see any new form take off.
That said, perhaps that means it's a perfect time.
Groups/Usenet has its limitations. Features invented over the last 30 years have value. Usenet can't be our YouTube or Facebook. But.. I refuse to believe open protocols got so much of the job done for so long, but the last mile requires a unicorn to platformize it.
There aren't that many hurdles to taking social media back. Login/identity. HN demonstrates that this can be relatively simple. Hosting. Not quite as simple, apparently. Moderation. Thats a stickier problem, but volunteer/community tends to be better... imo, than organisational moderation anyway.
There must be a way. Why not have freedom in social media again?
