I like earning best answers if the question asker really thought my question was the best. It also shows me that they care enough to come back and vote, after reading all the responses.
I honestly don't care about up or down votes. My views are what they are, even though I get more up votes than down votes a majority of the time. A majority of people agree with the advice I give and sometimes when I take an unpopular viewpoint, I'm not going to back down to spare someone's feelings. It is far more important to me that I actually furnish them with advice which will help them in the real world, not some online popularity contest that doesn't really mean anything in the end.
Best Answers are always appreciated especially if they helped the QA or are well thought out answers. I couldn't care less about up/down votes. If a feel a certain way about a topic, I will say it like it is.
