[This is from 2005] Blogs are now a media commonplace with regular mentions and appearances in mainstream media and an apparently exponential rise in use within education, knowledge management communities, and various forms of Web based self publishing. While definitions of what constitutes a blog are, in the manner of all such definitions, problematic, videoblogs pose this problem afresh with recent and rapid developments in this nascent field. My own views on video blogs are well documented, and have been for some time (Miles 2000). There are specific qualities or properties that a blog has which makes it different to existing forms of electronic writing and demonstrate that blogs are a medium in their own right.
