I read the other day that Bluesky, the Twitter competitor started by the founders of Twitter, came out of invite-only beta this week, so I signed up to park my name. I’ll probably never post there, and will never install the app on my phone. I never signed up for Mastodon, mostly because I never saw the point of belonging to a federated version of a service I never paid attention to anyway. Why have I done this, when I avoided ever being on Twitter? Hard to say.
