Actually, now that I have been thinking about this throughout the day, I think it would be a terrible idea to switch voting systems. Either way, small minded people are going to vote strictly 0's and 5's. Going to a yay or nay system would just force this behavior. Why should my carefully thought out critiques be limited because some jerkoff gives every porn a 5 and every stick drawing a 0? I am a dark reviewer, but if you were to see how I usually vote, most people get 2's or 3's.
I would rather see a running tab in the profile section of how many 0's or 2's or whatever I have given. For instance Gatorman has 1300 experience points, is dark, and has given 35 0's, 35 1's, 200 2's, etc.
PLEASE don't limit our reviews!
