It is! I’m not active on Mastodon, but there have been updates on X.
Please take into consideration that some people can't read these updates since Elon Rusk hindered access for non-logged-in users.
Given what a cesspool X has become, I would anyway encourage you to move away from X to Mastodon or Bluesky.
I have to support this notion. Everyone can read a Mastodon post. You can even subscribe to Mastodon posts without having an account. (via RSS)
For twitter... all bets are off... Additionally they don't like my security hardenings. (So I only see their whining page.)
I even checked X and, since I don't have an account, I can't see any posts at all. Nothing, empty profile. Please consider that not all people use it, and those who don't may be unable to see your updates.
