Advertising Platforms

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. http://widecircles.com
