A person is nominated on and voted for based on which members are known to deserve the award by the most people. I mean, really, Kishi's as popular as hell but if he got enough nominations to be up for "Nicest Member" people aren't going to vote for him, unless they laugh while doing it.

Popularity shmopularity. Belitting something as "a popularity contest" when others are clearly enjoying it is so emo. Pshaw.
