Basically blog is a kind of website in which items are posted on a regular basis and displayed in reverse chronological order so a blog could be 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 typically updated daily using software that allows people with little or no technical background to update and maintain the blog; a hierarchy of text, images, media objects and data, arranged chronologically. Postings on a blog are almost always arranged in cronological order with the most recent additions featured most prominantly. The term blog is a shortened form of weblog or web log. Authoring a blog, maintaining a blog or adding an article to an existing blog is called ?blogging?. Individual articles on a blog are called ?blog posts,? ?posts? or ?entries?. A person who posts these entries is called a ?blogger?. A blog comprises text, hypertext, images, and links (to other web pages and to video, audio and other files). Blogs use a conversational style of documentation. Often blogs focus on a particular ?area of interest?, such as Washington, D.C.?s political goings-on. Some blogs discuss personal experiences.?
