Integrating a blog ECMM 460

My area of specialization is industrial arts, and i can think of a few ways to incorporate blogs into my class. First of all it could be used as a way to create tips and helpful hints on specific problems that students are having in the class, i could post them once and it would save the students from wasting class time to ask questions down the road. I also think that a blog may be a good way to keep the parents of my students informed on what is happening at school.
