- the voting system is about what people want the truth to be, not the truth.
- the users can be very easily gamed in comments to vote one way or another just by the initial voting being negative or positive (aka most just vote with the trend)
- the opinions all come from a bias of urban and major metro area people. It's painfully obvious they don't understand any mindset outside of this one.
- it wasn't always this way.
I agree with you, the quality went down as the quantity went up, and it may be possible to use the comments, but using the vote data as a signal of truth is going to produce a terribly narrow minded AI.
