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 have a mastodon account but it’s completely useless for me.
the only thing i use twitter for is to follow updates and news from professional journalists and artists who are not on mastodon and likely will never be. if your job depends on twitter, switching to mastodon is not going to happen.
if i want to engage with random average people, i come here to lemmy.
