Stance on Wikitravel
Kasper has requested database dumps a long long time ago. So he was happy to find out about Wikivoyage, that does offer database dumps for download. Wikivoyage has successfully forked the German Wikitravel, and it is in the hands of a non-profit organization (unlike Wikitravel, which is owned by Internet Brands, a for-profit company).
He founded the CouchSurfing wiki in August 2006. He became very involved in CouchSurfing, was tech team coordinator for a while, was trying to move towards an open source codebase. In May 2007, when things didn't seem to work out anymore he and others started a site to create change: OpenCouchSurfing. So if you're a CouchSurfer, think twice before you get verified (which is merely a form of donation). Also, try BeWelcome instead, it's not as big but it's based on free software.
