A weblog - blog, for short - is a Web site that uses a dated log format to publish periodical information. The updates are frequent, usually daily, according to the site owner's editorial purposes - or whims. Blogs contribute to Web content by linking and filtering evolving content in a structured way and by establishing interlinked communities - the blogosphere - connecting people through shared interests. Bloggers can link to news feeds, personal journals, and topic-specific blogs of almost every sort. Blogging systems are emerging tools that make it easier to set up a blog; to update, distribute, and archive its information; and to enhance its functionality.
