I haven't used Twitter much in years really. But after switching to Lemmy during the reddit API debacle I thought I'd give it a go and am really enjoying it. I've set up a ton of filters to block out stuff I don't want to see, and joined a couple of instances for two different personas. I'm not using the official mobile client. On Android I use Tusky and Megalodon. Tusky is my daily driver and feels like how I remember the Twitter app from 7 or 8 years ago. Megalodon is nice for cross instance discovery, but has a couple of UI quirks that prevent me from using fully. My SO uses Ice Cubes on iOS and that looks pretty sweet. Personally I found the switch comparable to Lemmy. It took me a month or two to build up a good number of active people to follow to get to the stage of having an interesting feed. It also seems to have got a lot more active in the last week. When I have dropped into Twitter it's a dumpster fire on top of a cesspit. I don't think I could go back. I'd absolutely recommend giving Mastodon a go.
