Blog

A weblog (now more commonly known as a blog) is a web-based publication consisting primarily of periodic articles (normally in reverse chronological order). Although most early weblogs were manually updated, tools to automate the maintenance of such sites made them accessible to a much larger population, and the use of some sort of browser-based software is now a typical aspect of "blogging".

Blogs range in scope from individual diaries to arms of political campaigns, media programs, and corporations. They range in scale from the writings of one occasional author, to the collaboration of a large community of writers. Many weblogs enable visitors to leave public comments, which can lead to a community of readers centered around the blog; others are non-interactive. The totality of weblogs or blog-related websites is often called the blogosphere. When a large amount of activity, information and opinion erupts around a particular subject or controversy in the blogosphere, it is sometimes called a blogstorm or blog swarm.

The format of weblogs varies, from simple bullet lists of hyperlinks, to article summaries or complete articles with user-provided comments and ratings. Individual weblog entries are almost always date and time-stamped, with the newest post at the top of the page, and reader comments often appearing below it. Because incoming links to specific entries are important to many weblogs, most have a way of archiving older entries and generating a static address for them; this static link is referred to as a permalink. The latest headlines, with hyperlinks and summaries, are frequently offered in weblogs in the RSS or Atom XML format, to be read with a feed reader.

The tools for editing, organizing, and publishing weblogs are variously referred to as "content management systems", "publishing platforms", "weblog software", and simply "blogware".
