The recent launch of Facebook’s new text-only mobile website, 0.facebook.com, is a good illustration of the kind of non-commercial relationship that online social networks and mobile operators tend to form. Although 53 operators from 45 countries have agreed to waive browsing charges for 0.facebook.com users for at least a year, they are getting no payment in return from Facebook. No money has or will be changing hands between the social network and its 0.facebook.com operator partners.
