I guess theoretically and in some ways in practice. But I’m thinking more along the lines of “search through the web only returning results bookmarked with 2 degrees of trust” or something like that. Where each of the nodes are not documents but are identities- which may often tie 1:1 to a human
Isn't that basically newspapers? Journalists post articles and links to indicate they're at least interesting if not trustworthy, and usually under their own name. Webs of trust never worked for cryptography though.
