In all seriousness, I think it's time to accept that web search is currently broken as an idea, and we all need to go back to sharing our favorite links on personal websites. And we need to make personal websites a thing again, too.

Why is web search “broken” precisely? Do you mean that the web is too full of shit, that search engines are perverted for advertisement purposes, and that SEO optimization has nothing to do with quality content?
I agree with your proposition of a kind of web of trust.
