1. A display building system embodied on a computer-readable storage medium, comprising: a predictive component to determine potential topics of interest from interaction with one or more data locations; and a formatting component to aggregate and display at least one of the potential topics of interest and information pertinent to the at least one potential topic of interest retrieved from at least one of the data locations based at least in part on an expected utility and a current context comprising a recent or current application usage, the expected utility is evaluated as a function, f(I(p), S(p)), where I(p) is defined as a computed interest of a page p, and S(p) is defined as a computed navigation savings derived from the aggregation and display, the formatting component approximating a value of the page p to a user as a function of I(p), and S(p), the expected utility of the page being formulated as at least one of: 
 f ( I ( p ), S ( p ))= I ( p ) k1 *S ( p ) k2 ; 
 f ( I ( p ), S ( p ))= I ( p ) k1 +S ( p ) k2 ; or 
 f ( I ( p ), S ( p ))= k 1* I ( p )+ k 2 *S ( p ), wherein k1 and k2 are constants.
