Pixoto has the best grading system I am aware of

Given all the complaints about people voting against their competitors photos. Pixoto's system seems to have the pictures in an order consistent with their quality level most of the time regardless of this. In an imperfect world this is by far the best voting system I have seen. I think 90% of the photographers vote honestly because we really want to win not subvert the system and compete with inferior work. Well Done Pixoto!
