I only use X (via XCancel etc) to read the updates from things like the local train company that they only post on X. They aren't on Bluesky or Mastodon. When I tried Mastodon, I found it too politically extreme, it felt like walking into an angry students' union meeting. It never seemed to catch on in the UK, it surfed a couple of waves of dissatisfaction with X, but people quickly drifted away.
