Qassia

Qassia is a site that describes itself as an credit-driven intelligence engine coupled to a cascading tag-based web directory. You add items of "intel", short snippets or long articles, and get a backlink towards a designated site also. There's also a profit-sharing element, where you can earn money from any Google AdSense ads on pages showing your intel.

For adding and reviewing intel, or gaining referrals, you will also earn Qassia dollars. Currently, the more dollars you earn, the higher your websites will rank. In the future, these dollard may be used for purchasing advertising on the site.

Probably the most effective way of earning Qassia dollars is by submitting pieces of original, previously unpublished intel.
