Many voters indeed only vote for the acts they love, if they are indifferent with some acts, they will feel these acts are not influential. Many real voters just vote for acts are important to them, not important to whole music... This is problem
Probably we need to return to small committee or induct acts by category (pop/rnb/rap/metal/alternative)...
I do think some voters in open ballot tracker shouldn't be qualified as voter, they can not vote as unbiasedly as possible
The public voting pool is more problem than nom com to be honest
