"Reality advertising is a trend in the making. Some corporations are beginning to think using an ad agency might not be the best way to create an ad campaign. Ringo.com, a networking site like Friendster and Ryze have put out an RFP to members of Fark, a community weblog, asking Farkers to create an ad campaign for the company. Ringo is offering a $1,000 prize to the winning entry."
This certainly has the potential to undercut BBH :-) It will be interesting to see what the submissions are like.
