A blog is an abbrivatted version of the term Web Log. It 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. “Blog” can also be used as a verb, meaning to maintain or add content to a blog.Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketches (sketchblog), videos (vlog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media.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.
- Personal Blogs
The personal blog, an ongoing diary or commentary by an individual, is the traditional, most common blog. Personal bloggers usually take pride in their blog posts, even if their blog is never read by anyone but them. Blogs often become more than a way to just communicate; they become a way to reflect on life or works of art. - Corporate Blogs
A blog can be private, as in most cases, or it can be for business purposes. Blogs, either used internally to enhance the communication and culture in a corporation or externally for marketing, branding or public relations purposes are called corporate blogs. - Question Blogging
This is a type of blog that answers questions. Questions can be submitted in the form of a submittal form, or through email or other means such as telephone or VOIP. Qlogs can be used to display shownotes from podcasts or the means of conveying information through the internet. Many question logs use syndication such as RSS as a means of conveying answers to questions. - By Media Type
A blog comprising videos is called a vlog, one comprising links is called a linklog, a site containing a portfolio of sketches is called a sketchblog or one comprising photos is called a photoblog. - By Genre
Some blogs focus on a particular subject, such as political blogs, travel blogs, house blogs, fashion blogs, project blogs, education blogs, niche blogs, classical music blogs, quizzing blogs and legal blogs (often referred to as a blawgs) or dreamlogs.
