The more I see how people use downvotes, the less I like them as a feature in general. I make a point to not downvote things anymore.

• Everyone can upvote, which already brings the most popular content to the top. Why does the system need another dimension to it?
• If I disagree with someone enough to act on it, it’s my rule to explain why. A minus one is often nearly useless as feedback.
  • Then, when I’ve replied, what’s the point of downvoting? Everyone can read my thoughts.
  • Replies can also be upvoted, for people who think truth comes down to a battle of internet points.
• If I honestly believe something is bad or harmful for the community, it should probably be reported, not (just) downvoted.

Downvotes as they are seem like bad design on the human interaction level.
