I only posted two questions on meta, both fact based and both about the way MO is supposed to work. Today, I realized that I have received three down-votes. I have a feeling about down-votes (and up-votes) on MO, but, absolutely no idea about the meaning of these on meta. So my question is: how should one interpret a down-vote on meta, in particular, when the question is as I described above?
When points are not involved, such as on community wiki questions and on meta, votes are mostly used for sorting: upvote what you think is valuable or important, downvote what you think is of negative value or distractive. This way, topics that the community finds most important or otherwise valuable rise to the top of this list.
