As a follow-up to our discussion on Friday about the responsibilities of online journalists, bloggers, or historians there is a great article on Slate.com about Wikipedia and its anonymous editing format. This article discusses a new online tool, which the graduate student who invented it calls Wikiscanner, that searches the computer IP addresses of the persons who edit pages on Wikipedia. Wikiscanner was able to trace the IP addresses to places like corporations, law firms, and religious institutions like the Church of Scientology. This article raises so many interesting issues that were discussed in class like disclosure (and whether it should be required or at least encouraged) and whether Wikipedia readers are actually scrutinizing the material they read.
