I'm against downvoting because it is mostly abused... however, I like your idea that downvotin should include a "reason stated" for each downvote.

Since downvoting is not going away though, I would like to see vote power COMPLETELY removed from it's use. There is more justice in a completely free market than their is in a falsely monopolized one... the whales would never allow it, but the ideal situation would be that EVERYONE regardless of steem power has the same downvote power as everyone else. It would equalize the playing field for fighting ACTUAL of abuse and it would help the dumber whales to actually act in their own (and the blockchain's) LONG TERM best interest rather than in the short sighted manner they currently mostly bumble around in.
