I had been on reddit for more than a decade, and it takes time. And it takes people posting and commenting. As a relatively "normal" person, I don't even really fully understand what lemmy/fediverse is. I'm barely getting a handle on what instances are. And from what I gather, it could be a really cool place.
But it'll take time. And people. So I suggest just staying calm, up and down vote things as you see fit.
I don't know if I'll ever go back to reddit, but it definitely was my main source of information on subjects that I have interest it. I've stopped using Facebook, I only use Twitter to interact with podcasts.
I worked for lumber liquidators, and their point of sale software seemed to be surplus navy because if you dug deep enough you could order nuclear sub parts.
I'll have a big thing typed out and then think about if anyone would care. Usually I didn't think anyone would. So many discarded drafts.
