Classroom Blog Spots

I intend to use blogging in my classroom as a way to communicate reasons for my methods to the parents, fellow faculty members, and a way for me to have feedback about what others think.
Students can use blogging in the classroom to communicate. As a teacher I need to have every sort of teacher/student communication available. I need feedback from the kiddos, telling me what they got out of the lessons taught, how they are applying the lesson, and most importantly what they aren't understanding.
Blogging is also a way for the student to decompress, IE: issues they don't necessarily want to talk about. It is a source for me to go to if I suspect the student is having issues with other homework, other students, or at home. It is a source of counseling.
