Blog

A blog (a portmanteau of web log) is a website where entries are written in chronological order and displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.

Blogs provide commentary or news on a particular subject such as food, politics, or local news; some 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), sketchblog, videos (vlog), music (MP3 blog), or audio (podcasting), and are part of a wider network of social media.

In May 2007, blog search engine Technorati was tracking more than 71 million blogs.^[1]

Blog's Types

There are various types of blogs, and each differs in the way content is delivered or written.

By media type

A blog comprising videos is called a vlog, one comprising links is called a linklog,^[11] a site containing a portfolio of sketches is called a sketchblog or one comprising photos is called a photoblog.^[12] Blogs with shorter posts and mixed media types are called tumblelogs.

An Artlog is a form of art sharing and publishing in the format of a blog, but differentiated by the predominant use of and focus on Art work rather than text.

A rare type of blog hosted on the Gopher Protocol is known as a Phlog

By device

Blogs can also be defined by which type of device is used to compose it. A blog written by a mobile device like a mobile phone or PDA is called a moblog.^[13]

Genre

Some blogs focus on a particular subject, such as political blogs, travel blogs, fashion blogs, project blogs, legal blogs (often referred to as a blawgs) or dreamlogs. While not a legitimate type of blog, one used for the sole purpose of spamming is known as a Splog. A Slog (Site or website log) is a section or 'slice' of a regular business website, which is seamlessly integrated within the regular website structure but is produced with blogging software.

Legal status of publishers

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 PR purposes are called corporate blogs.

Blog search engines

Several blog search engines are used to search blog contents (also known as the blogosphere), such as blogdigger, Feedster, and Technorati. Technorati provides current information on both popular searches and tags used to categorize blog postings.
