A personal journal published on the Web. A weblog, or blog for short, can take many forms. Some are online scrapbooks for pasting links and quotes from items found on the Web; many act as personal diaries, often illustrated with digital snapshots; and some are more like digital soapboxes, providing a platform for airing opinions and commentary, either about the world at large or on a specialist interest. Some of these formats have been adapted for commercial publishing or marketing, or as a knowledge management tool, and other business adaptations have been suggested. The unifying theme is that the user (known as a blogger) adds entries using a simple online form in their browser, while the weblog publishing software takes care of formatting the page layout and creating archive pages, RSS feeds and other supporting functions.
