Teaching Blogging

I dont think I am ready to teach blogging to my students. I was very skeptical about blogging because they are there for the world to see. I find that information for class is acceptable to post because it is an insight into my opinion on academic subjects. I think I am still in Phase 1 of the Thinking About Teaching Blogging to Your Students?. The only con for teaching blogging to our students is the assumption that all of our students have computers. This is a problem because it may make some students feel less fortunate than others by knowing they dont have a computer at home and they cant go home and continue to work on blogging.
