I'm watching the podcast and they are discussing what terminology to use to talk to people about the fediverse in a way that's not confusing. But I don't really see terminology as a problem honestly

pleroma => software which runs a social network platform

ilja.space => social network platform

fediverse => social network

I don't think I ever had any one being confused about that. Sure, they may not really see a difference in their mind between "social network platform" and "social network" at first, but that's the beauty of it, it's not confusing. And the moment they realise there's a difference, they seem to quickly understand that. You don't have to suddenly start explaining how this single thing you were talking about is actually 3 different things.
