There are lots of good suggestions already. If you want to explore how the different threadiverse platforms display your posts, look into Lemmy, Piefed, Mbin, and NodeBB.

kbin.social no longer exists but the project has continued as Mbin. For fediverse discussion communities you have !fediverse@lemmy.world (on Lemmy), !fediverse@piefed.social (on Piefed), !activitypub@community.nodebb.org (nodeBB)
