A search engine (Scour) that pays you to search.

Scour is a social search engine that provides web, image, and video search results aggregated from Google, Yahoo, and MSN. Scour allows users to upvote or downvote and comment on their search results, thereby forming its own search rankings based on user feedback while rewarding users with corresponding points. Unfortunately, it does not support Chinese keyword searches.

Users can accumulate points through searching, voting, commenting, or inviting friends to join. 6,500 points can be redeemed for $25... however, you need at least 50,000 points to request payment, which can be redeemed for a Visa Gift Card or paid via PayPal.
