Originally it was called web logs — a personalised online journal. Blogs are a means to publish and communicate to a web audience. A blog is a website where a person writes on anything that pleases him on a continuous basis and has an option to keep it open for others to read. New entries show up at the top. One can comment on these or link to them or send an email to the author of the blog. At an individual level, a blog is a personal diary. At another level, it can be collaborative space. In short, a blog is what its host wants it to be.
