It's not PageRank that worked, it's anti-induction that worked. PageRank did not work, as soon as it faced resistance.

You really are a "glass half empty" kind of guy aren't you.

I am not really trying to be negative for the sake of being negative here, I am trying to correctly attribute success to the right thing. People get "halo effect" in their head because "eigenvalues" sound nice and clean.

Reputation systems, though, aren't the type of problem that linear algebra will solve for you. And this isn't too surprising. People are involved with reputation systems, and people are far too complex for linear algebra to model properly.

True, but not particularly relevant. Reputation systems like karma will not solve the problem of who to trust or who to pay attention to -- but they are not intended to. Their task is to be merely helpful to humans navigating the social landscape. They do not replace networking, name recognition, other reputation measures, etc.
