13. A computer-readable storage device having computer-executable instructions stored therein, wherein the instructions are executable by a computer to perform the acts of: identifying one or more secondary sources of content based at least in part on an overlap of one or more links associated with the secondary sources of content, and links associated with a set of one or more primary sources of content, wherein the overlap indicates an extent to which the secondary sources of content comprise links that are comprised in the set of one or more primary sources of content, the links associated with the set of one or more primary sources of content are comprised in a topic linkset, and generating the topic linkset comprises detecting that a first set of the one or more of the links associated with the set of one or more primary sources of content is not relevant to a topic associated with the topic linkset, and excluding the first set of the one or more links from the topic linkset; assigning secondary source scores to secondary sources of content, wherein said scoring is based on amount of overlap of linkset of the secondary source and the topic linkset of the primary sources; assigning URL scores to the links associated with the primary and secondary sources of content by adding the scores of each of primary and secondary sources that links to the URL; and generating, based at least in part on the URL scores, and generating, based at least in part on the URL scores, a source of content comprising one or more recommended links selected from the links associated with the primary and secondary sources of content.
13. A computer-readable storage device having computer-executable instructions stored therein, wherein the instructions are executable by a computer to perform the acts of: identifying one or more secondary sources of content based at least in part on an overlap of one or more links associated with the secondary sources of content, and links associated with a set of one or more primary sources of content, wherein the overlap indicates an extent to which the secondary sources of content comprise links that are comprised in the set of one or more primary sources of content, the links associated with the set of one or more primary sources of content are comprised in a topic linkset, and generating the topic linkset comprises detecting that a first set of the one or more of the links associated with the set of one or more primary sources of content is not relevant to a topic associated with the topic linkset, and excluding the first set of the one or more links from the topic linkset; assigning secondary source scores to secondary sources of content, wherein said scoring is based on amount of overlap of linkset of the secondary source and the topic linkset of the primary sources; assigning URL scores to the links associated with the primary and secondary sources of content by adding the scores of each of primary and secondary sources that links to the URL; and generating, based at least in part on the URL scores, and generating, based at least in part on the URL scores, a source of content comprising one or more recommended links selected from the links associated with the primary and secondary sources of content. 14. The computer-readable storage device of claim 13 wherein the computer-executable instructions are further operative to cause the computer to perform the act of filtering the generated source of content to include links associated with a predetermined time interval.
