Why did my question get a downvote?
Currently, there is no consensus about whether to provide tooltips for the voting buttons (especially the downvote one). However, the community now includes quite a lot of questions that attracted downvotes and sometimes this created long debates in comments and flagging.
I would like for us to define a few answers for the "Why did my question get a downvote?".
This should help us in providing a reference to a downvote reason, if one "standard" one is appropriate.
