The term ‘blog’ is a shortening of the word ‘weblog’. So, what is it?
A blog is a kind of online journal or diary which is displayed in reverse chronological order. A blog may contain it’s own specific information, or it may contain links to other websites. Previous blog posts are stored and archived. Blogs are about why, not so much about the actual content. They are mostly a means to share information, more conversationally rather than content oriented.
