Generally answer them, nice to add an opinion to a community, and see how others answer. Plus it keeps me posting more things since I don't really reply much or keep up with the forums anymore ;/ to much stuff keeping me away from following along
Posting a reply here means i do. I do vote when the poll applies to me and to see others opinion on the same poll that applies to them. It's interesting really, a way to kill time.
I most of the time love to come here to read the awesome and erotic hentai manga's, and I always vote on the polls, I see as no harm as taking a couple of seconds to vote and answer.
