I understand your concern, but it's really just a reminder to vote the article up if you enjoyed it. I frequently read good articles and then forget to vote them up because something else catches my attention. I really doubt anyone is swayed to upvote an article they didn't think worthy because of this message. Just the opposite: some hacker types get worked up because they seem to be allergic to promotion of any kind, and thus won't upvote the article, even though they would have otherwise. But I'm betting that the balance of people who upvote because they liked the article AND because they were reminded outweighs the anti-promotion crowd. Either way, I don't think it's a big deal. Sorry if it offended you.
