What is your opinion abut usability in the context I gave? From some other source I got this:

Zap and Osada do one thing (social networking) and do it well. Use Osada if you want a really good ActivityPub server, and use Zap if you want or need nomadic identity and much stronger privacy than the fediverse can offer. Use Hubzilla if you actually know what a ‘platform’ is and want to build something great (decentralised communities and cities with shoppes and businesses that all respect your freedom) rather than than just waste your life in idle chit-chat.

What says you?
