You seem to be vastly underestimating the time-cost of running a successful, pertinent, engaging, active and informative online community that isn't held together by a starting group of close friends or partners who have fun doing a particular activity together.

For a bit of practical grounding, consider that simple "clan" (or "guild" or whatever other term they pick) websites for online gaming communities that somehow manage to go above 100 members, a paltry number compared to what I believe is the target size of userbase of this wiki, often require at least three or four active administrators who each put in at least 5 hours of activity per week in order to keep things running smoothly, prevent mass exodus, prevent drama and discord, etc.

The goal isn't just to make a wiki website and then leave it there, hoping that people will come visit and contribute. The goal is to go from a bunch of low-profile scholarly stuff to the scientific AI risk version of TV Tropes, with a proportional user base to the corresponding target populations.
