Great. That's exactly what I said in my original post -- hire someone specifically to do that. Problem solved. Now your junior/mids don't have to explain that. But that's not the career trajectory of every developer, let's be honest.
If someone's going to deny me a promotion for linking a wikipedia page that answers a basic question and completely ignore my technical contributions, I absolutely do not trust that place has the best interests of its developers in mind and is likely driven more by politics than anything else.
