Andrew Sullivan, has, I think, hit upon one of the key virtues of the blog as a tool for journalism; he writes in his “Blogger Manifesto” that “Peer-to-peer journalism, I realized, had a huge advantage over old-style journalism. It could marshall the knowledge and resources of thousands, rather than the certitudes of the few.”
Blogging-as-journalism then shares the advantages of open source software—you have hundreds, perhaps thousands, of bug finders, fixers, and coders working because they want to. And I think this “open source” effect is one of the potential side effects of using blogs for instruction. You are helping students find a voice, a personal commitment to their words and thoughts, and you are teaching them to think about audience, one of the central requirements of good writing. These are all Good Things.
Since I started really thinking about blogs—and deliberately reading and researching them—I’ve slowly realized that one could argue that my central Celtic Studies Resources site is a blog, a blog with categories, and stories.
