I think this is it. On Lemmy and some of Reddit it doesn't matter who you are, as long as you behave yourself and bring thoughtful discussion with you. Twitter was more about following tweets from famous people groups, and finding people that outwardly display doing interesting things, so they would want more famous people to increase adoption.

yeah this is a bit different. It depends on where the best conversation is. I think we'll see a pretty large boom over the next few weeks, then a pretty solid decline, but if the devs are smart about it, some solid steady growth from there.

Over time we should be angling for "Oh yeah, I forgot I had an account over there, maybe I should check it out" as people see more and more links
