Yeah, keeping the content flowing will be the most important thing, and it’s much less daunting than taking on moderator duties. Everyone on Kbin/Lemmy right now is basically an early adopter, so they might need to take more responsibility to keep momentum up. It’s too much to ask people who usually just read news on their niche subreddits to suddenly start up their own community here, but everyone can take one step “up the ladder” so to speak, and we’re already seeing this to some extent I think. Lurkers trying their best to be commenters, commenters putting up their own posts and regular posters starting their own communities.
The thing to get across to people is that you don’t need to understand it to use it. Hell, that goes for most things. The average person has no idea how an internal combustion engine works but can drive a car just fine.
