Wikitravel and World66, two user generated content travel sites each using the same Creative Commons license (Attribution-ShareAlike 1.0) have been acquired by Internet Brands, the operator of carsdirect.com and many other .com properties.

It’s great to see Internet Brands’ confidence in a business built on CC-licensed content, particularly under a BY-SA license, which permits forking, even for commercial purposes.

Congratulations to World66, Wikitravel, and especially to Wikitravel cofounder Evan Prodromou, who has been an active supporter and constructive critic of Creative Commons from the beginning.
