I use Facebook, but keep it very private. Not a useful place to connect although it does have times when it is useful. Not a big fan though, and I find plenty I don't like.
Instagram - not a place for decent social interaction. Likewise Threads. It started with promise but is full of crap. The diaspora has spread.
Mastodon feels like I am shouting into the void and there is not even an echo. Ghost town would be an understatement.
Bluesky is a bit exclusive as it is invite-only at the moment. Starting to gain some traction among educators though, so it is showing a little (slow-moving) promise. I will be focusing a little more on building this one.
I am using LinkedIn a bit more, it seems to be reasonably OK in terms of the people I connect with, but we don't have fabulous discussions like I had on G+ and Twitter/X. Has the world moved on and left me feeling more anti-social media? Or have I moved on? We'll have to see what happens a year from now if any of these other sites gains traction. It's a shame to have to leave good channels of communication behind. If anyone has any better suggestions for places to connect with like-minded souls, hit me with them!
*SIGH* I'm now bored of Insta, Threads etc. I am sticking to Mastodon and BluSky as well as my Facebook...
