First Blog Ever

The idea of blogging is frightening to me. If I wanted to open myself up to the world, I would have become a writer, but I didn't, I  became a teacher instead. So how can I use blogging in my classoom? I think my AP students might take advantage of blogging to have conversations about the literature we are studying, but I'm not sure my other students would be interested in discussing literature after school hours. I'm sure students would enjoy creating projects by blogging since they are much more computer-savvy than I am.
