This is an interesting question.
I would say I'm just a casual user. I don't feel important (not in that way) that if I left, Phuks would have an empty hole in its heart. I'm involved in some small niche subs and a bit of shitposting. I'm just a casual user. I don't have a kevdude sense of entitlement. I know my place in the community, and it's great. I wouldn't want it any other way.
On smaller websites like this its easy to give admin to all of your friends. Before you know it, everyone has a stake in management of it. I think there has been a fine balance struck between the number involved in management and the user base itself.
I'm interested to hear the responses
The important people are those that actually keep the website hosted and the code usable. I think all other users taken individually are dispensable, myself especially.
