Wow, that's some bit of linkbaiting in that article, pointing to other techcrunch articles and a lot of pointing towards skift.com, nytimes and some other sites.

The entire article talks about three different websites, and it contains 0 links to any of them. http://wikitravel.org is the old one, http://wikivoyage.org is the newer one, and the last one is not decided upon yet, but the definitive source about that is: https://meta.wikimedia.org/wiki/Travel_Guide
