?

I often find that the questions I've answered are summarily abandoned after a short time and certainly before voting begins. The asker doesn't bother to pick a best answer, and almost no one votes on the answers. Is it unethical or shady, then, to vote for my own answer in order to increase the 'Best Answer' rating? Would it be better if I refrained from doing so unless I really thought I had written the best answer, or is this common practice? I'm of two minds on the issue, and I'd like to hear some opinions on how other people commonly approach the matter, and why. I don't want to be dishonest with the community and conceited, but at the same time I did work at answer the questions and it would be nice to get something for the trouble instead of having it abandoned. (If no one else bothers, I might as well get the points?)

I'm honestly not sure what to do here. Then I realized I'm on a site that specializes in answering questions, so maybe it was time I used it from the other side. ;)
