Another essential element: we are going to have to track the degree of confidence in influence scores and trust attestations. I might say I think Bob is an expert in some topic, and I’m 99% sure bc I’ve known Bob for years; or I might say I think he’s an expert, but I’m only 5% sure bc it’s based on a single brief interaction. And the Grapevine might say Bob is an expert in something with 99% certainty bc lots of highly trusted individuals independently arrived at the same conclusion; or only 5% certainty bc it’s based on a single attestation by only one user who is multiple degrees of separation away from me.
