Argublogging is an application that allows users to write arguments supporting or dissenting from any text on the web through a bookmarklet. It posts the arguments to the user’s blog and also includes a map of the debate in the argument web, “a richly structured interconnected web of debates and disputes, arguments and counterarguments.”
The respond-to-this-argument feature looks easy enough to use, although support is currently limited to posting to Tumblr and Blogger. The visualization of the “argument web,” though, looks more like something those with an academic background in argumentation would get the most use of, at least in its present form.
That said, for journalism, or any discipline involving argument, there is a lot of potential value to users in the ability to visualize the history and strands of an ongoing public debate. Someone who could use this or other argument-mapping tools to track and explain how a debate has evolved would be quite valuable to a news organization.
