People have always felt the need to express themselves and cave paintings are arguably the earliest blogs. We now have tens of millions of blogs on what is the biggest, most exciting, expanding cave we have ever seen – the web. Blogs are unashamedly honest and personal. It is this that makes them so readable but of what relevance are blogs to learning?
