What is a blog? Not only that, but what are blogs used for? If you dont know the answer to that, where have you been for the last three or four years? The word blog is short for web log, and is strictly a record of the changing content of your website. People who were interested in the content of your site would register to receive your blog, and would be informed whenever a page on your site was updated.
