A blog is short for “web log” but it’s really just an online diary. Blogs typically display time and date stamps along with a section for readers to post comments. A blog is basically a journal that is available on the web. The activity of updating a blog is “blogging” and someone who keeps a blog is a “blogger.” Blogs are updated frequently and it requires little or no technical background to update and maintain a blog. Postings on a blog are arranged in chronological order with the most recent additions featured most prominently.
