I nominate
In Forum Advertising. Web Advertising 2.0 and
PostingDirect: Paid Forum Posting Service
InForum Advertising shows the transition that advertising is going through as people are becoming more ignorant of banner and related ads and "personal" advertising is becoming more influential than ever.
PostingDirect takes the concept of forum posting and puts on a web 2.0 spin. Forum posters may work on any forum they like and get paid for it and forum owners have hundreds of posters waiting for work.
