Getting set up for my students to Blog

Tonight I am just testing to see how it goes with Blogging.  My students will be reading The Hunger Games and I thought this would be a great way for my students to record their thoughts of what they are reading instead of journaling.  Of course I am a little nervous as I have never blogged before, but I am assuming this is just like writing in a journal.  I have a feeling my students will be able to teach me a thing or two on this.
