Bluesky is a social media very much like Twitter was - created by the same people who made original Twitter. It has some good features but is still in 'Beta' stage. It's still being fitted and doesn't have DMs yet for e.g. I'm only really active on Bluesky, now, and that's mainly because my circle from twitter migrated there. So, there were people I knew there straight away and the conversations could continue... For me, it's more active than my me.dm and X - which is basically my Ex, now, and I only keep it going for the DM facility...
