Hi!
Q1:
a) My first question is, why is it called UserAuthority? Why not something like UserGraph ?
A1: Because the "graph" is only a way to visualize it, the "matrix" (of principle eigenvalues) is a mathematical representation of "the state of the follows network on steem", and "authority" is what it all boils down to: how much authority / influence / visibility does each account have seen from a probability distribution perspective
Q2:
b) Are you guys in contact with Steemit Inc. about it?
A2: Yes!
Q3:
What is their opinion about your solution?
A3: they didn't delete my account yet, so I guess everything is OK! ;-)
(You'd have to ask Steemit Inc, I'm not going to comment or speculate about the opinions of multiple people within the Steemit Inc organization).
Q4:
c) What are your plans in general with UA? As we need a Hardfork for this, the whole steem network need to come together to decide about it.
We're going to deploy it as a service. Stay tuned for more!
