Just when you were starting to figure out what a Blog is, along comes Wiki

Next up in the Economist Tech Quarterly is Blogging goes to work which introduces the curious to wiki's.

Two useful links in this regard are : What is Wiki and, for the more technically inclined, the Wiki Engines Page.

What is a wiki? Where as a blog is primarily a linear (most recent first) and single author web space, a wiki is more category / cross-link driven and multi-author collaborative web space. Some blogs can be viewed by categories, and Wiki's can be viewed by most recent or by author, but generally blogs are a functional subset of wiki's. Both are variations of very simple content management, with the focus on content, informality, trust, and ease of use. The word comes from "wikiwiki," which means "fast" in the Hawaiian language.
