This week, I went over to Bluesky and asked people who'd left Mastodon why they left, and lots of people told me. I grabbed the replies and crunched them and wrote up a summary. I think it's really interesting and often kind of wrenching.

@kissane super interesting. I can see what people mean about being yelled at, but only so much. I know I've been reminded to add alt tags to images. But that's a good thing IMHO.
As for disocoverabiliy. I just discovered you. So yeah. I get it, but like it here :)
What if your client software reminded you instead of a person taking time out of their day to specifically tell you to shape up? Would that vibe better? I think it would for me.
