The issues that the article covered around 'being specific' not only applies to presenting start-up idea of course. I've seen the same issue appear in resumes, during interviews and conducting performance reviews - all situations where people start talking in abstract/generic terms and fail to specifically mention their skills/achievements. In my experience, learning how to be specific has the biggest effect on improving your resume, interviews and performance reviews.
