What are the concerns of blogs and blogging in education?

I believe that the concerns of blogs and blogging in education is that you are never sure what you are going to get, or who is going to contribute. Blogging allows opinions to come from anywhere and sometimes opinions are shared that are not necessarily “school appropriate”. Having access to blogging will also allow access to blogging sites that are not regulated and could be used in a wrong and harmful way by some students. Students have to be educated on how to correctly blog and how to identify blogs that are not for educational use.
