I often '++' a question because, while it may be poorly posed, the question engendered an interesting thread of responses.

I rarely '--' a node for any reason, much less 'style' or "English grammar/spelling". If I don't like a node, I exercise my third option -- I ignore it.

I look at a '--' vote as the 'Big Stick' and only haul it out very occasionally and then only for the really egregious cases of Troll-ism or Flame-baiting. Perl Monks is composed of Adults (intellectually if not chronologically), and I have come to expect a certain Standard of Civility of Discourse. Re-enforcing that behavior is really my only criteria for a negative vote.

We have all come here to learn. We are all Students here.

Update -- fixed typo. (Thanks fenLisesi).
