MySpace

MySpace is social networking site allowing users to display networks of friends, personal profiles, blogs, groups, photos, music, and videos.
It allows relatively unlimited amounts of modification, though does require knowledge of scripting in HTML and CSS.
This does create some issues, as people who do not have a great knowledge of design can make their pages very hard to read, make them look unappealing and more than often detract the user from actually viewing the content as they are so distracted with background and text colors.
Though, if done correctly, pages can look fantastic.
One issue that I personally do not like with websites is the constant need to scroll down web pages, MySpace pages are renowned for the user to scroll down a long way to view all the content. Other sites such as Facebook, have a far better layout, are more user friendly, and filter the information into a more readable and efficient format.
