Wiki

Washington Post said Blogging Clicks With Colleges Interactive Web Pages Changing Class Participation but they really were not talking about blogging, but rather about Wikis.

The wiki, which got its name from the Hawaiian word for "quick," is the scrappy little brother to the blog, an interactive Web page that can be changed by anyone who stumbles upon it. While blogs let people publish their thoughts online, wikis take things a step further, creating freewheeling, collaborative communities: Students can edit one another's work, bounce ideas around or link to infinite other Web sites...... Wikis, including interactive encyclopedia Wikipedia, have been around for several years but they're just on the cusp of becoming mainstream; as the technology improves, they're popping up in a few classrooms and offices, and people are finding all sorts of uses for them.
