I've been following net neutrality issues pretty closely and this is the first I've heard the term "zero rating". I didn't have a clear understanding of the term after reading the article, since I wasn't sure if zero rating was the exemption or if ISPs were exempting services from the zero rating. The wikipedia[0] entry helped, also referring to it as "toll-free data" which cleared up the confusion for me. [0] http://en.wikipedia.org/wiki/Zero-rating http://en.wikipedia.org/wiki/Zero-rating
