I don't like the clickbait title at all -- Mastodon's clearly going to survive, at least for the forseeable future, and it wouldn't surprise me if it outlives Xitter.
Still, Mastodon is struggling; most of the people who checkd it out in the November 2022 surge (or the smaller June 2023 surge) didn't stick around, and numbers have been steadily declining for the last year. The author makes some good points, and some of the comments are excellent.
I kinda want to give it another try. There was once a blogpost posted here (i think) about basically "how to have fun on mastodon", something like that, but i can not find it anymore. Anybody remember this and got a link?
Can't recall what the title was, but I do remember reading a guide of sorts that essentially boiled down to "start following tags first, you can filter people later".
