I have an account on Mastodon: johndcook@mathstodon.xyz. Note that’s @math… and not @mast…
One advantage to Mastodon is that you can browse content there without logging, while Twitter is becoming more of a walled garden. You can browse my account, for example, by going to the URL
https://mathstodon.xyz/@johndcook
There’s hardly any content there at this time. I’m deciding what I want to use the account for.
Another advantage is that Mastodon, or at least the Mathstodon instance of Mastodon, supports LaTeX content via MathJax. This would be convenient if a thread has a few equations.
I’m certainly not going to create 18 accounts on Mastodon accounts like I did on Twitter. I’m thinking of maybe using my Mathstodon account to post highlights from my Twitter accounts, all in one account.
I’m concerned with where Twitter may be going. I do not plan to leave, though the site could change my mind.
I also have a Bluesky account, but I have no idea what if anything I’ll do with it. My handle there is johndcook@bsky.social.
