I always like to start with a good foundation. It must come from the years I spent working in construction. If the foundation wasn't started correctly nothing else lined up and that made things pretty miserable. So I would like to start this the same way.
Blogging Pedagogy - While I was researching this topic I discovered a pretty cool Prezi,
outlining the pedagogy of blogging. This was created by Christopher Long, a Professor of Philosophy and Associate Dean at Penn State University. What I learned by viewing Dr. Long's Prezi was that a blog is a publishing platform that can be used to build community and ultimately blur the lines that have previously defined a classroom and the length of a student teacher relationship. A blog becomes a place that allows a broad community to interact and exchange ideas in a form that otherwise would not exist.
Blogs seem to differ based on application. What I mean by this is that when used in education they are a place for students to discuss assignments and projects. My interest is a little different, that of instructional design. In this arena blogs become a place to share best practices, ideas, and tools. One example is this blog,
http://christytucker.wordpress.com. The particular article linked here talks about how the number of blogs available have increased over the years. It also includes links to many of them, which makes the point of blogs being a place to share ideas and tools. Another example would be this post from upside learning that highlights the top online resources for instructional designers to keep up with.

I believe blogs are useful and an opportunity to collaborate and share outside of more traditional forms.
