To Blog or Not to Blog?

I may use a blog in my future classroom. If I end up using a blog in my classroom, it will be to communicate classroom activities and schedules to parents. I would like for students' families to understand what our class is learning and working on each week to help students expand their learning at home. However, I believe that if a teacher is going to use a classroom blog they should be consistently updating it and creating new posts. I do not plan to use a blog in my future classroom until I feel that I have enough time to manage and update a blog enough so that it is always displaying current information for my students and their families!
