Habits formed on SO would lead me to comment on anything I was downvoting anyway, but it feels like something of an imbalance that deters me from active participation in some conversations -- see my comments on the recent thread about SSC deleting the blog.

Edit: I also can't edit my reply to the parent of this, and regret my reciprocation of the name-calling... I wouldn't editorialise this out, just identify that it's an example of unhelpful behaviour.
