Reading selection: What is a blog?

A Blog is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order. Blog were usually the work of a single individual, occasionally of a small group, and often were themed on a single subject.

 Blog can also be used to maintain or add content to a blog. Some microblogging services offer features such as privacy settings, which allow users to control who can read their microblogs, or alternative ways of publishing entries besides the web-based interface. These may include text messaging, instant messaging, E-mail, digital audio or digital video.
