While one would think so, because it would make sense, the reasonable or logical thing isn't always done. My guess is they don't because that would be chilling for the punditry etc. They only rate them by the number of followers and viewers, not performance. For sure those guys who were telling us that netflix and Amazon were just fads and to wait for 20 dollar google, would have garnered devastatingly low rating if there ware such a ranking system. Too bad no one seems interested in creating a performance rating. Oy vey!!!
