Sometimes going on the Internet can be like walking into a library that has 1000's of floors, no card catalog and no distinguishing guidance between the "fiction" and "nonfiction" sections. While the Internet has allowed everyone to have access to information that the traditional mass media may have filtered in the past, it also causes problems with determining what is trustworthy. Especially when it comes to travel. I mean who do you trust? Who really KNOWS what the cultural differences are, and who is going on stereotypes and biases? For example, after a week with a friend in Paris, I felt that the hospitality and warmth the people had so graciously offered had bucked the stereotypes that they were rude. My friend, on the other hand, shockingly revealed on the last day that she didn't like the French and that theory was based on her husband's experience without her a year before and the advice he offered before the trip. So you have to take into account that many people are going to go to the tried and true mass media sites.
