On that part, I do agree with you. I do not like mastodon just because I'm not a huge fan of the micro-blogging-focused user experience, but I do agree that there's value in a platform not imitating Twitter but having some of the UX. Likewise, I think that there is value in another platform that would attract Twitter users. I think it could just be a separate mastodon instance that is modified to fit said user base.
