I don’t think users are going to participate in these sorts of experiments long term. People are signing up now out of fear and anger and hope but Mastodon still lacks the user base — people for you to follow and people to amplify your posts. (Partly because it’s still a fraction as popular as Twitter and partly because the hosts all seem to be blocking a different half of the other hosts so even if two people are both on Mastodon they may not be able to connect.)
If, on top of all that, people are expected to tolerate “a lot of iterations” before things work right I see them leaving. Let’s not forget that the Twitter/Mastodon mode of interaction can be pretty toxic so there needs to be a big carrot for people. Mastodon doesn’t have it. Twitter barely did tbh.
