I'm not complaining, I'm just curious.
I wrote an answer to the question about humanely killing a squirrel and was surprised to see that my answer had not bumped the question to the top of the question list.
Was it because the Q had been highly downvoted (minus five) or because an answer (downvoted to minus two) had been accepted already, or a combination of the two? Is there some combination of downvotes that makes a question so not-interesting that a new answer cannot push it to the top of the list?
