I actually have much more faith in Google's capacity and CDN than I do in Verizon's history of sleaze.
After all, Google doesn't have a conflict of interest, Verizon does. The better Netflix and YouTube get, the closer I am to canceling my Verizon TV service.
Why would this be the case? It is only in Google's best interests to provide the best streaming service possible. It's not like they have any shortage of servers, bandwidth, or funds with which to do so.
This is the problem with such ratings systems -- they're inherently one-sided.
