One more data point in line of my Whither Web 2.0 Social Networking Discussion which questions the revenue models of web services (with web social networking as a focal point): An on-line service the scale and scope of Microsoft's Online Services is running into red ink of proportional scale. It lost $471 Million per last quarter. The clear and present issue is not whether a profit may be turned at some even-large scale, but what will change about the business model and how will that affect users?
