[Useless]

Obvioulsy, sites where the user has some level of control over the content are very popular today. However, allowing surfers to add the links themselves is a huge error. It's begging for spam and links to unfriendly/illegal sites. If you could create two separate classes of users - one webmaster and the other surfer, you could then deny surfers the ability to add links while allowing them some other less important freedoms. Maybe voting? On an adult site, you never want to allow surfers to add outgoing links.
