I've been on reddit a long time, over 17 years, and I'm a member of some private subs that happen to have some quite influential users in them. It would be really interesting to open those up to the public to see what reddit influencers are saying in closed spaces, and the amount of gaming etc. that goes on between prominent users you see all across the site.

Admittedly, at least the subs I'm in are relatively quiet these days, but in years gone by they'd basically decide what was going to be popular, who was going to mod which subs etc.
