Classroom blog

I am starting this blog to possibly use for my class this fall.  I am looking for feedback.  What I would like to blog is my weekly email information.  What is coming up as far as homework, some school wide events, and some links the students might need to help them with what ever we are working on at the time.  I started an old blog a really long time ago, and never did anything with it.  Does anyone out there use blogging with their class?  How does it work and do you have any insights to add?
