At their best, blogs give an individual the chance to interact with and become part of a collective that both shapes and is shaped by his or her thoughts. Blogs, by their very nature are tentative works in progress. They have the character of playfulness, which is core to the new culture of learning. They can be experimental in nature, used to test and refine ideas. But at their base, they serve as a means to kick-start a collective around conversations about ideas that spring from the personal.
