That's a pretty good description of peer review. It varies, but generally the people chosen know the topic and are good representatives of the community, even if only 1-3 people. For good venues (journals and even conferences), I think the biggest limitation is not the people, but the information contained in the paper. You can't answer all questions and show every last detail. People are frustrated with academics, but academics are frustrated with how journalists and readers interpret their results.
