I can’t speak for others, but when I joined I was definitely confused by instances, federated internet, moderation variances, and how to operate the various ~ 4 beta apps I downloaded at the same time.
I’m definitely not a tech normie, but it was still unfamiliar and I would never have migrated if I hadn’t been fed up with Reddit.
Most people don’t want to have to look up guides to figure out how a system works, they just want to download an app that their friends all use and move on with their day. Blocking instances you don’t like? Doing research to find a “home” instance? Ain’t nobody got time for that.
Maybe, but those questions are part of the normal daily zeitgeist. Everyone is exposed to those concepts and services through natural osmosis, but when I wanted to join Lemmy I got an app and I didn’t realize until I started trying to use it that it was a distributed system. Then I’m like, wait what? And I had to go read some stuff about it. Wasn’t anything too crazy but I was confused at first.
