On all of the other SOFU sites a downvote means The question is unclear or not useful. However, here on meta, a downvote has become a sign of I don't agree with the question, suggestion, feature request, bug, etc. being described in the question.
- What does a downvote on Meta really mean?
- What other reasons do people downvote on Meta?
- Why is it okay for meta to redefine the meaning of the downvote? The tooltips and instructions are all the same here on meta.
Note: I'm not saying I disagree with the practice, just curious.
