Then you can also do SEO analytics on site for domain authority too, that tells you roughly how many people use it vs other software. Or check how old a site is, how old a video is etc
I think what recsys really should be trying to target is finding the group most similar to your tastes, and then picking based on the outliers of that group. The goal being to find something within your tastes, but far enough from your normal to be interesting
Recommending based on star personalities preferences, is I think, a way of approaching this idea: why would you want to know what the average item is? You want the best one.
I'll be sourcing recommendations from the silent majority of experts as well (https://prog21.dadgum.com/143.html).

OT: I checked your profile but couldn't find an email to contact you. It'd be cool if I can shoot an email once in a while to brainstorm.
I don't mind if the site is stagnant.
Scale, curation, combating spammed submissions to AJ, etc. might be the biggest things if the site gains momentum, but if the site remains a hobby project indefinitely (which I think is totally fine regardless of popularity), then it's absolutely not needed.

Living in San Francisco, you hear just how narrow this focus gets, with 20-somethings walking down the sidewalk making conversation about how to monetize this public accommodation or that human impulse. It strikes me as an odd mixture of funny and repellent, and at least some of those folks will grow up someday.
It does mean a lot of folks are concentrating on a crowded path that smart people will avoid. I mean, sure, if your big idea is in enterprise storage or EV, that's not happening with investment. A recommendation website? If you're not building to flip (which would be stupid anyway), it would be crazy to go begging to build.
