I've had a bit of fun using MediaWiki to power a few websites! Check out cyborganthropology.com, caseorganic.com/wiki, and indiewebcamp.com for a few examples. A default install of MediaWiki looks like wikipedia.org, and you probably don't want your website to look like that. However, MediaWiki is a powerful platform for building your site, even if it's just being edited by one person!
This German radio program was a group project of Aaron Parecki, Joel Young, Kirsten Arbogast, Jude Kirstein, and Viktoria Wenslöw during a German 311 course at the University of Oregon. We had a great time putting it together and presenting it, so I figured it deserved a place on the Internet. You can listen to the whole thing here.
