Mastodon has the unfortunate adolescent problem of being not Twitter but not yet fully matured into its full potential. Teenagers and Mastodon alike rebel agaist their parents in order to discover who they are. Before they sort this out they try a bunch of contrary behavior and eventually they discover what makes them them.
Is Mastodon Mastodon because it doesn't have full text search, because it doesn't have an algorithm feed, because it is decentralized, because it doesn't have quote replies, because it has a different user base with different relations?
All of these, and not all of these. Mastodon will, eventually figure out which ones make it itself and which ones don't. Maybe in that process it reinvents itself countless times or maybe it coalesces around a strange attractor in social-feature-space. We dont know the results without running the experiment and figuring out what full text search means to Mastodon is running the experiment.
