Blogging 101

A weblog (usually shortened to blog, but occasionally
spelled web log) 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 can be hosted by dedicated blog
hosting services, or they can be run using blog software on regular web
hosting services.

Like other media, blogs often focus on a particular subject, such as
food, politics, or local news. Some blogs function as online diaries. A
typical blog combines text, images, and links to other blogs, web
pages, and other media related to its topic.
