Are My Students Bloggable?

After reading J. Black's article entitled Thinking about Teaching Blogging to your Kids? I'm personally stuck on phase 2. I'm trying to think how blogging can truly be useful for my students. I teach at a Title One school and I may have three or four students who have computers with internet access at home. I've been taking my class to the computer lab every week for the past few weeks, trying to get them comfortable with the keyboard. I'm just not sure that they're ready. They're not very good at writing and I'm not convinced that an unstructured format where they're potentially just responding back and forth to each other will help them become better writers.
