In the business, this is known as "linkbait." For better or for worse, controversial topics tend to attract traffic, and links from other sites. Search engines like Google place tremendous value on links, and tend to send pages with lots of links plenty of traffic. So the implication is this - create a controversial Weblist that gets people talking. Other sites will link to it, search engines will notice it, and your Weblist will get traffic that earns you cash.
