I had thought about something like this, sort of a combination of karma scores and netflix/pandora-style recommendations for ranking user content on sites like HN. I could say 'I like what tptacek has to say' and give your content a higher precedence for ME, rather than for the whole of the site user base. Others could say 'I dislike what tptacek has to say', and you get a corresponding drop for THAT USER, not everyone. Now add a chain - if I 'like' you, all that you 'like' gets a smaller, but significant bump for me, and so on. Add in 'OSCP' style repudiation if the source of your trust for someone changes their mind for any reason.

Moving this into authentication/trust - how do you 'start' something like this at an Internet scale, assuming actively hostile, nation-state level players, such as in this article? It seems very chicken-and-egg for something as critical as encryption and protection of important content.

Just thoughts - it seems there's some big issues I'm missing though, such as initial seeding for 'new' users en masse. I can also see the code to keep track of all the trust vectors, etc. becoming VERY complicated...
