The long list of National Tourism Organization links that you saw was actually to determine how many of them use social media. The answer is quite a few. I could find out information about 80 countries that used at least one social media (Web 2.0, Travel 2.0 or whatever you like to call it) platform. The most popular ones are Facebook, Twitter and Youtube but Flickr at number four. Here is the list of links, if you find an error do let me know. The attempt is to write an academic paper around this, this is just raw data, but I think a first (to the best of my knowledge) compilation of such links in the context of NTOs. I wish I knew to make better tables in word.
I moved the links to the Social Media like Youtube, Flickr, Twitter and Facebook of the NTOs. Sorry for the inconvenience.
