Hi dear @davidblackwell, i have once heard is not good to upvote your post but sometimes you can't even help it.
Your is even better you get up to 10-30 cents, i can remember making 4 posts that got nothing at all, to get 2 cent is most times not easy.
Personally is not bad for me, afterall you can't upvote a post more than once, as long as you extend a helping hand to others.
