What are the downsides?

Because blogs are often produced and maintained by individuals, they can include biased or inaccurate information. Users visiting a blog might see it as factual or authoritative when, in
fact, it is the online equivalent of a soap box: a place to speak and to be heard. Unlike chat rooms, blogs are unmediated and therefore offer a different type of venue for individuals to express
themselves and air their opinions, ideas, and attitudes. While this may be acceptable for a personal blog, it might be inappropriate for a blog hosted on an institutional server. Intellectual property is another area of concern for higher education, given the implications of hosting blogs that might include content that has been used without proper attribution. Blogs are also highly volatile. Bloggers can edit or delete posts, and this transient nature can make blogs difficult to archive or
index. In addition, the time-limited relationship of students to institutions influences the length of time a student blog should be hosted, yet removing posts from the blogosphere once a student has graduated could confound those who linked to the post.
