				| Community Model 
 
 
  
    | The viability of the community model is based on user loyalty. Users have a 
    high investment in both time and emotion in the site. In some cases, users are regular contributors of content and/or money. 
    Having users who visit continually offers advertising, infomediary or specialized portal opportunities. The community model 
    may also run on a subscription fee for premium services. 
 Voluntary Contributor Model -- similar to the traditional public broadcasting model -- the listener or viewer contributor 
	method used in not-for-profit radio and television broadcasting. The model is predicated on the creation of a community of users 
	who support the site through voluntary donations. Not-for-profit organizations may also seek funding from charitable foundations 
	and corporate sponsors that support the organization's mission. The web holds great potential as a contributor based model 
	because the user base is more readily apparent.

    | Knowledge Networks -- or expert sites, that provide a source of information based on professional expertise or the 
	experience of other users. Sites are typically run like a forum where persons seeking information can pose questions and 
	receive answers from (presumably) someone knowledgeable about the subject. The experts may be employed staff, a regular 
	cadre of volunteers, or in some cases, simply anyone on the web who wishes to respond.
