Happy land
We;ve become so BS oriented in our society that we don't want to hear bad news. Those people you call overly negative may be the types that deconstruct everything naturally. Sure you wouldn't put them in sales, but in the connect role they are indispensable. Trying to convert every introvert into an extroverted glad handling smiling JA is ridiculous, but something I've seen in the last few years: It's a concerted effort to destroy the geek. Not everyone is a politician or wants to be one. May be if we had more nitpickers, accidents with the space shuttles wouldn't have happened as a case in point.
