How many of you are also on BlueSky?
Mastodon still has the discoverability problem where I can't see random posts I might like because I'm on my own server and can only find new people to follow when someone I already follow forwards something I find interesting enough to investigate (which then leads to the other problem where I can't see a random person's old posts in my client without having to view their profile on their own server).
I don't really want to run my own server and keep it up to date, but I can't join someone else's server with my own identity (I tried living on SDF's servers and they kept forgetting to renew their TLS cert). I wrote my own ActivityPub server but it was too hard keeping up with the private "Mastodon API" that every mobile app uses, so I gave up and switched to the official Mastodon server software which is huge and constantly changing (and breaking).
I hate that Twitter died and fragmented everything.
