I always just say Lemmy, it sounds much more appealing than the fediverse for the uninitiated. Also I don’t really use any other fediverse platforms, so Lemmy is basically the entire fediverse for me.
But I still think the fediverse is a decent name/cool concept (federated universe), plus it’s already got a decent amount of brand recognition so it would pretty rough to start over with something new. It’s a fine name for people who are already familiar and have been using it for a while, it just sounds kinda weird when people first hear about it.
I’m not. I wish they were but I’m not surprised, there’s some good reasons why people might not want to wear one.
