Yep, that is literally me. I am not particularly techy or whatever and I came here because RiF shut down and the maker said they would be on lemmy.world. i had no idea what that meant but i made it here.
Much googling was involved and after i made like 4 accounts on different instances, bumbled around, settled down and learned to subscribe to stuff, i subbed to communities specifically about the fediverse and finding new communities. I also tried like 3 different apps and aettled on Liftoff so far.
I still havent figured out how to reliably see mastodon or kbin stuff or if i even want to.
I can see how most people wouldn't bother and have no idea why any of this even matters. I still find reddit much easier to use (and important for ongoing world events like the war in ukraine, where it isnt about what we can aggregate but where posters from that conflict put their content originally, a huge amount gets posted directly to reddit and they dont have time to sit around debating the finer points of internet usage), but philisophically i understand why the fediverse is important.
Also learning sbout the concept of defederation (as it regarded Beehaw) was a brainmelter and i felt like i was missing out on "content" be ause of how big it was. My other issue was around not undersranding who runs all these instances and quite frankly having no reason to trust they wouldnt do some crazy stuff themselves.
