There is a big difference between discussing the negatives and simply making negative, sarcastic and/or snarky comments. While I tend to leave up most posts, those that serve no useful purpose may be removed, especially when put up by a poster with little or no track record or a history of little but such comments. My approach is that those who have contributed to the discussion have earned the right to the occasional negative comment, but if you're looking for a place just to complain or be negative, then head over to the other site.
