This paper describes "argument blogging", by which the authors mean the creation of arguments based on and reacting to arbitrary web resources (i.e. a blog post). This paper leverages existing argumentation technologies, such as the Argument Interchange Format (AIF), the AIF Database (AIFDB - an argumentation-specific MySQL database), and Dialogue Game Description Language (DGDL), as well as the World Wide Argument Web (WWAW - a collection of internet-connected arguments).
The authors talk about the server as a point of failure, and indicate how a distributed system could be seen as an improvement. Yet they also see the strength of WWAW as a "unified point" (both of failure and success): by archiving distributed arguments, they are not lost piecemeal, whereas the "integrity of a chain of arguments distributed across the web" could be easily harmed by the loss of one or a few of those distributed arguments.
