content is turned into cash. Hot Nacho pays regular people three dollars to write an article on a random topic and then persuades sites like Wordpress.org with a high Google Pagerank to host thousands of these articles and link to them. In Wordpress' situation, they chose to use a CSS trick to hide these links far off the edge of the web page where humans using browsers cannot see them. Hot Nacho then pays the site a flat monthly fee for performing this service.
