A blog is a term for a "Web log" which is usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order.
Many blogs provide commentary or news on a particular subject. A typical blog combines text, images, and links to other blogs or sites of similar interests. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, but can include photos, videos and audio.
As of December 2007, blog search engine Technorati was tracking more than 112 million blogs.
There are many different types of blogs, differing not only in the type of content, but also in the way that content is delivered or written.
- The following are some of the common Blog types:
- Personal Blogs - an ongoing diary or commentary by an individual, is the traditional, most common blog.
- Corporate Blogs - used internally to enhance the communication and culture in a corporation or externally for marketing, branding or public relations.
- Question Blogging - questions are submitted in the form of a submittal form, or through email. Many question logs use syndication such as RSS as a means of conveying answers to questions.
- Genre Blogs - blogs that focus on a particular subject, such as political blogs, travel blogs, house blogs, fashion blogs, project blogs, education blogs, niche blogs, and classical music blogs.
Wordpress and Blogger are the most widely used, but a search will uncover others which are free and others requiring a fee.
