I see not only me often wondering What was the cause of the minuses? I think there are several potential reasons, like:
- wrong / false
- language quality
- not agree
- upd: not funny
- upd: boring
I assume the reason to have downvotes and upvotes is to increase the quality of content. I think it's awesome. I learn a lot from it. But to allow users (including myself) to improve their posts, it would be nice to have statistics at downvoted blogs and comments, showing the downvote reason.
Having said that, I consider this not just another feature request, but something that may substantially increase user content quality and in the same time help users to improve and develop. Isn't that what's CodeForces for?
