I believe the antidote to this is simply acknowledging small communities curate the best content, so essentially marry many small decentralized communities on a searchable platform. Anonymous but karma/identity weighted profiles, curating and debating lists of their favorite things around a single topic.
Aggregate them into a single master index with nice UI, then pay out equitably based on performance.
There’s a lot of questions on preventing spam and fraud, and I think the further away you get from “high ticket products” the more you avoid that problem, but it can’t be worse than Google: in one you’re relying solely on magical AI and links, the other you can have as much magical AI and links as you want, but you also have user accounts which maybe invited each other and can vouch for each other at a cost, votes that can be weighed by all sorts of factors, and basically a much richer graph of self-moderating people to back the index.
Working on something like this at the moment!
