Honestly, I hope to see it thriving, but for that to happen, there really needs to be a move away from a virtual monoculture where there is 1 main implementation with 95% of the users(masto and forks), and more towards a model where many implementations are designed for different purposes. I also think there needs to be more thought put into the social model of it, where things like locking or at least limiting comments, non-"note"(post, toot, etc) kinds of posts are done, and really I think that the ideas we have now just need to be expanded upon and more set in stone.
