I am still “on X” because my account was banned and I literally cannot delete the account… because it’s banned.
But since I know that’s probably not the type of use you were referring to, I know others that still use it for scientific communications (e.g. announcing publications from their group and following those from others) and generally don’t care much or think about the fact that Elon is heading the platform.
I don’t know what to do with this information.
