Special thanks to Professor Hsinchun Chen, Associate Editor-in-Chief of IEEE Intelligent Systems, for the invitation to contribute to their forum on “trends and controversies in AI, E-government, and Politics 2.0.”

The short piece was published in the September/October 2009 issue (volume 24, number 5) and a PDF is available here and on my “conference papers and published works” page.   In it, I discuss the Blogosphere Authority Index and some of the challenges confronting web researchers.
