What is a web log or blog?

According to Wikipedia:

A weblog (now more commonly known as a blog) is a web-based publication consisting primarily of periodic articles (normally in reverse chronological order)…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. Wikipedia (2005, September). Retrieved September 18, 2005 from: http://en.wikipedia.org/wiki/Blog
