The discussion about privacy is changing as users take control over their own online data. While they spread their Web presence, these users are not looking for privacy, but for recognition as individuals -- whether by friends or vendors. This will eventually change the whole world of advertising. The current online-advertising model will become less effective, even as it gets increasingly sophisticated.... This approach (called behavioral targeting and already in service by ad networks that track users through so-called tracking cookies) undercuts traditional online publishers, who employ content to lure users and to sell adjacent ads....This does not mean that traditional online advertising will go away, just that it will become less effective. Value is being created in users' own walled gardens, which they will cultivate for themselves in real estate owned by the social networks. The new value creators are companies -- like Facebook and Dopplr -- that know how to build and support online communities.
