I've noticed that a lot of brand new answers have already been upvoted by the time I get to reading them (presumably by the author of said answer). I have not been upvoting my own answers. Unfortunately as a result (perhaps because the question asker hasn't gotten around to reading through answers) I have a few answers with a score of 0.
What are the 'ethics' of "seeding" your own answer with an upvote? (Also: am I mistaken that you are capable of upvoting your own answer?) Finally, if you can upvote your own answer, why would you ever NOT upvote your answer (outside of general humbleness) - presumably you think the answer is good because you bothered to invest the time in writing it.
