PayPerPost (PPP) is a website which helps content creators such as bloggers find advertisers willing to sponsor specific content. The advertisers create opportunities ("opps") that describe the content they are looking for (e.g. feedback, reviews, buzz, creative, video). The bloggers (sometimes referred to as "Posties") then choose opportunities in their area of interest.
