I am positive that Stephanie Hurlburt is smart and talented. I never intended to question those things. But question the onslaught of speakers who have don't appear to have a good backing for why they are experts other than "they spoke at conference X, therefor...". Making a single accomplishment does not automatically make you a expert. Experts are those who have spent years honing their skills and demonstrated success time and time again. An expert is not somebody who is mirly smart and talented and driven. Those qualities combined with time, successes and failures is what makes an expert an expert.
