I love the concept of a wiki. An open-source website where anyone can post, verify, and elaborate on any type of information they are interested in. The best known wiki is www.Wikipedia.com but today I am highlighting a travel wiki called clickAcity.com. At clickAcity, users can leave travel reviews, tips, and update existing travel information to reflect changing global trends. From the latest nightclubs in New York to Cleopatra's Mine in Egypt, clickAcity provides travelers unique perspective based on real life recommendations.
