I got super frustrated with Mastodon because of this. I’ve tried a couple of instances with no luck. And hilariously, I have to think that the furry folks are either having the same problem finding a home, or they are stalking me, because everywhere I move, shortly after, a ton of furries appear and do introductions. Furry stuff is not my thing, but I can appreciate how they might have a hard time finding a good place to settle.
I think that app choice makes a difference, too. I would guess that most people on mobile picked one or two apps to try, and if their picks weren’t great (or the user was too impatient to wait for improvements) they called the whole experience shitty and bailed. Those of us committed to the move hung on and waited for our apps to get better.
In my case, I grabbed every ios app I could find and tried them all. Some were not so good, some were good and improving at a lightning rate. Living through those growing pains is worth it to me, especially when the improvements are crazy fast. I’m mostly using Memmy now, and I’m really happy with it. I only have one tiny, unimportant issue with it involving text selection, but it’s nothing compared to how good they’ve made this app so quickly. Memmy is a large part of why I stick around.
