Yeah, Usenet is what my brain mapped Lemmy to. You get your feed and post through your server. You read posts from others on other servers. Each local server decides what feeds it will carry.
Of course, there’s no central hierarchy for the communities like Usenet had.
Yeah, my hope is the small learning curve to join the fediverse means we don’t end up with the bulk of the active posters on reddit.
My fear is that Lemmy is about to see some attacks the fediverse isn’t ready to defend against.
