Hmmm, so whats going to happen when the 4.7, 4.8 star etc sellers profiles appear next to 5.0 star sellers? Who would you pick as a service provider? If you needed a new roof on your house and you consulted Yelp, and found numerous roofers with 4.7 etc reviews that were amongst roofers with 5.0 star reviews, you would hire the 4.7 roofer because ?
