If I was doing that kind of work at Wikipedia and was a real place to go to, they would’ve already snipered me.
A good many people operate with the assumption, often heard and repeated, that “knowledge is power.” So they guard what they perceive to be knowledge, and do so on their own terms.
They do not know you. Somehow they are in a position to exert contrary efforts over your hard work. That has to be frustrating to say the least.
Anyway, given your willingness to apply yourself to facts, there must be some way you can do this kind of work and gain the satisfaction of seeing fruit. Have you considered teaching (if that is not something you do already)?
