In their own words, "Qassia is a credit-driven intelligence engine coupled to a cascading tag-based web directory." Qassia is actually a combination of a Social Bookmarking, Social Media, and Wiki site. The way it resembles Social Bookmarking sites is that they both are tag based and users can submit the data by adding tags to it. It is also at the same time a Wiki kind of site as you can submit your own unique article which they call it "Intelligence". You can create a profile there and add your site which gives you a dofollow link. Once you setup your account, you can submit your own unique articles and every time you add intelligence, you get backlinks and credit. More credit you get, higher you rank for your site! You can get unlimited backlinks from Qassia. You can also add your Adsense publisher ID and get 100% of Adsense revenue. I setup a Squidoo Lens with more detailed info.
