Information
A blog is often a mixture of what is happening in a person’s life and what is happening on the Web, a kind of hybrid diary/guide site, although there are as many unique types of blogs as there are people.

People maintained blogs long before the term was coined, but the trend gained momentum with the introduction of automated published systems, most notably Blogger at blogger.com. Thousands of people use services such as Blogger to simplify and accelerate the publishing process.

A blog (short for weblog) is a personal online journal that is frequently updated and intended for general public consumption. Blogs are defined by their format: a series of entries posted to a single page in reverse-chronological order.Blogs generally represent the personality of the author or reflect the purpose of the Web site that hosts the blog. Topics sometimes include brief philosophical musings, commentary on Internet and other social issues, and links to other sites the author favors, especially those that support a point being made on a post.

A Web site (or section of a Web site) where users can post a chronological, up-to-date e-journal entry of their thoughts. Each post usually contains a Web link. Basically, it is an open forum communication tool that, depending on the Web site, is either very individualistic or performs a crucial function for an organization or company. There are three basic varieties of blogs: those that post links to other sources, those that compile news and articles, and those that provide a forum for opinions and commentary.
