vote1 is super bad (-:, vote 5 is the thing with artistic value

Bill here, is a man who I trust to vote professionaly (say I see he uploads quality images, so I estimate he has Aesthetic filling)

John on the other hand, I know nothing about him, or I even know he has no clue about photography.

This is more like general logic. I guess, avg(vote * weight) would give me right/smart result about image quality. Or m'I missing something ?
