I'd like to address the market risks: Did you know, that large retail sites increasingly employ people to post merited positive, and no-merit negative reviews to funnel consumers into a buying decision? And, by economy of scale, they do this in volume -usually massively overwhelming genuine on-site reviews. Working out the impact is left as an exercise for the reader.
