The life span of weblogs is investigated with reference to Lanham's view of the "Economics of Attention" and Hardin's conception of the "Tragedy of the Commons." It is advanced that the unfettered buildup of inactive blogs is leading to a surfeit of information which effectively disables potential readers due to an excess of choice. One factor indicating healthy activity in a blog is postulated as being sufficient feedback from readers that leads to the emergence of an ongoing social network. This is viewed as an example of a virtual technology shaping social groups. Research-in-progress is outlined that refers to observations of various film music blogs derived via the case study method, featuring a focused commentary on one that has subsequently been a victim of death in the blogosphere. In this case, the forced extinction of a blog is taken to be an example of human foibles influencing the download spiral of one instance of a virtual technology.
