Not very (as you can tell from the delay in my reply). I hang out in Mastodon, mostly. But I’m a responder, not a poster, so my interactions are limited by three amount of content I have to react to.

But that’s ok. I don’t need a huge social media time sink in my life.

I’m not subscribed to much yet. I browse the general feed; I tend to add stuff organically, rather than go searching for it.
