However, by the time the site was just weeks old, Spears popularity had shifted from teen to tween, meaning that her popularity was now limited to 9 to 11 year-olds who don't have the same degree of disposable income that the older teens have. This shift in identity requires a complete change in Youtopia's advertisers and the markets they are targeting. The site provides tools for users to create their own fan sites for their favourite celebrities and these sites then act as a catalyst for community building. With this content model, the site's producers are immune to the changing tastes of their target audience. The site changes with the users.
Teens are far more interested in each other than they are in anything else.
This fact may give another model the edge over the Youtopias and AcmeCitys of this World Wide Web. With teens the user-produced content model is still king. They dictate the agenda and they can change the agenda at will. In this model, the users of a particular site write the content for their peers to consume and then discuss in forums and chats. In this model content and community are inseparable.
