My son just glanced over at my phone where I had @ivory open (which I used as my #GotoSocial) client and asked "what's that?"

I realized I didn't know how to answer. Previously I would have said "Mastodon", but while it's hard to tell, my account is now hosted on a #GotoSocial server, so Mastodon's not correct. So what then?

"I'm checking the Fediverse?" "ActivityPub?" "Micro blogs?"
