Hall of Fame voting is done by only Hall of Famers so it is not as similar as to this as you make it out to be. As for Kc, I personally didn't vote for him because I felt it was too soon. At that point, he's had just 2 great years of play and only 1 year where he was acknowledged with accolades. He's had another great campaign in 2014 so his resume does look a lot better and he's no doubt a future Hall of Famer.
As for the current list of nominees, they are as is. I've made it as fair as possible to those who have played and played well. It's up to the players to vote based on performance rather than popularity. If the results turn out to be just awful then we will have to reevaluate the voting system.
