Occasionally, one hears observers say that a “killer app” is required to get billions of people interested in using the Internet, assuming other barriers also are diminished (service cost, device cost, language, knowing how to use the Internet).
Others might say it is very clear that social networking is the killer app already in place. “Demand” is not the issue.
In other words, "end user demand" on the part of people who do not routinely use the Internet is not really lacking. People know what they want to do. We just have to build networks to deliver it, at prices people are willing and able to pay.
