Doc, thanks for the great words. In the short-term, the ratings system can be irrational as investors sometimes vote via knee-jerk reaction. However, in the long-term, good members will be properly rated more often than not.
I've been there as the dissenting / minority opinion before. In the short term investors can get upset because you are a potential threat to their investment. In the long term, they typically turn out to respect you if your posts are well reasoned and - god forbid - right about potential negative aspects.
Regards,
George
