The blogging discussion

The big discussion. How do we use this as an educator. Honestly the only good thing I think it could be used for is allowing students to discuss a topic they are studying, a book they read, and that maintaining discipline about what is being posted would be knowing that anyone can read it their teacher, their parents, grandma, ha ha. Grandmas usually have a way of keeping you in line. Typically students would not write anything they would be embarrassed for their grandma to read. Would anyone care to disagree? Rochelle
