DSterner, one of the student bloggers, had an insight that really struck me:
The blog diehards are like fans of politics--political junkies. They are not unlike fans of other media. A lot of people watch a popular show like Lost, but then there are the hardcore fans who consider every clue to solving the show's mysteries and debate them among themselves, including the various references that the show's creators put in the episodes--hints and connections that might be lost on a more casual viewer. The show can be enjoyed by both types of viewers.
Is politics another form of fandom? Or maybe the question is: Has the blogosphere created a political fandom?
