Blogs in the classroom

I believe there are pros and cons to blogs in the classroom. I think if I did something with blogs in my classroom, I would want as much as possible to be completed in class. Not every one of my students may have the internet or even a computer at home. I would love to use blogs as a way for my students to express themselves and learn how to use the computer for more than just games and playing.
Before taking the class, I did not know a lot about blogging. I had no idea it could be used a tool in my classroom. Whether we realize it or not, technology is being used more and more everyday in every aspect of life. If we as teachers do not start getting our students on board with it, then who will?
