I think this is a neat idea! How to make it work though…
From my perspective, the fediverse is mostly about pioneering. Venturing to new places where the others (twitter, reddit) have been for years and were established. We‘re still fighting trolls and stans from time to time but far less than on the reddit side.
There is corporate disobedience as we walk away from the known, the enshittified and the boring to brave places where new people might spit in our face or name you their bff.
I mean, the fediverse is really as if someone had hacked twitter, sold the code to 100 people and now they all spin up connected clones. Same with reddit. Benefit: one clone goes down and the service still exists.
If you need more inspiration i‘d suggest asking chat gpt. :)
