I have just joined Bluesky, but it does seem to be very worthy and very focused on the big issues of real life, so I don't know how long I'll last over there.
I'm doing it again already, spreading myself too thin. That's it now. No other sites of social media allowed. I already know I can't keep up with one, let alone two. (Or three, in fact, since my non-writing real life friends and activities are all on Facebook.)
