I opened a question on stackoverflow which eventually, after setting a bounty, got answered. Under my point of view, it was a valid question: it was about a problem I was facing related to a computation process/operation, I was including my source code and requesting aid to understand a problem I was facing. Anyway, the question got downvoted down to -2.
I understand the vote as an "interesting for the community" index, and I like to contribute to my best. So, having a downvoted question is something I dislike a bit, as you can imagine.
To improve my future questions, I would like to understand what I did wrong. I would apply to the downvoter's good will to understand it, but I cannot find anywhere who they were, so I cannot ask them directly.
Would you please take a look at my question in stackoverflow and speculate about the possible reasons for the downvote received?
The question is this: Hex grid map with PyQt4
Thanks!
