Please be advised that the following paragraphs contain links to websites with explicit content. If you feel offended by it or are not of legal age you should skip this article completely. User generated content is in my opinion the number one argument why Web 2.0 sites are that successful. It does not matter if you take a look at Youtube, Twitter or Myspace to realize that they would not be that successful if it were not for the users that would feed them with new content.
