We have to blog, why?

I think we are using the "blog technique" so we have a wider audience. If we post our writings and other things (video, music etc.) we will write differently because we know that others are seeing it, not just our teacher. So our techniques of writing will hopefully get better. It will also be easier for me because when I get home, I go straight to my computer. I have to check my messages, maybe play some games, but now I can go straight to doing homework on the Internet. I also feel like this is safer than a "myspace" or "facebook" because who would want to look at a 9th grade English class, now that I think of it, maybe some nasty perverts will.
