Yes, interesting point. As you say, a twitter platform may need personalities, prominent cultural figures / personalities (I would say more content creators rather than influencers, as I think the myth of influencer power is overrated, but that's a different issue lol). Whereas reddit/forum Communities -style would need to attract those groups, migrate some, be known to others which have already been deplatformed or censored. It's a somewhat different beast of adoption lol, and definitely also difficult to pull off, but probably somewhat more imaginable.
