Discovery is just the worst, lemmy has a problem with it as well but it's somehow just amplified on Mastodon. There is basically no way for me to organically find things I would be interested in. If I don't already directly know how to find someone or something I want then I'm never going to come across it.

Compare that with blue sky which has a basic Discovery algorithm that I can pretty easily tune to what I want using filter lists I was able to very quickly get it to understand what type of artists I'm interested in following and what type of content I want to see and what I don't want to see and through that I have discovered a bunch of artists I otherwise never would have known about.

Mastodon works good enough if you only want to follow very specific people that you already know about and can easily find but if you're hoping to actually organically discover content I found it awful. The feeds for instances are pretty generic they don't try to tailor to your interests it's just a dump of whatever is on that instance or whatever it's Federated with depending on how you view it which basically just guaranteed it was always filled with stuff I couldn't give less of a shit about.

It's very possible that the interface has changed since I last used it but at least when I used it the interface was pretty clunky and not very fun to use at least in my opinion, I did host my own instance for a little while and used a Twitter bot to copy the art of artists I liked over to a mastodon feed but you know all those Bots broke a little while before it became X so ended up giving up on that
