To blog or not to blog as a teacher

Honestly, I really don't want the controversy surrounding blogging as a teacher. It is not worth it to me to risk upsetting parents or other teachers with the opinions that will be expressed on my personal blog. I would not want my blog to effect getting a teaching job or promotion. Also, I am planning on becoming an early elementary school teacher and to use blogging as an instructional tool is not really practical at that age. I can definitely see it being useful for a junior high school or high school teacher. Especially because that is how most students in that age group communicate. If I did have a blog as a teacher I would use it to share course related resources with fellow teachers, but I would not want a personal blog that is unrelated to my job. Not just because of the controversy that can surround it, but also the time it requires to keep up a blog.
