A vote by me generally means: "Yeah, I like what (s)he wrote". It can be a question, an answer, or a wisecrack.
I never downvote, and will vote for any new monks posts, even if they are dumb questions. I generally vote for all poems, snippets, and meditations; since someone took the time and trouble, to post it, they deserve a point to show them "it was not in vain".
