Did anyone out there give a try to Wide Circles or WideCircles. They are new word of mouth advertising platform, apparently they can push massive amount of messages through social network mediums like forums,blogs,wiki's and so on. They say that they only bill for posts active for minimum of 5 days and price seems pretty affordable. I am going to give Wide Circles aka WideCircles a try since I am tired of PPC fraud.
