I have never been convinced that they deliver any real value through their articleinsider.com site...they claim not to be an SEO company...but in fact that is exactly what they do...and they run a very aggressive sales organization and are constanly spamming advertisers at Overture and elsewere for leads...got to it give to them for ingenuity and aggressiveness..they have built out a very profitable business...but I still don't think the value of the traffic they deliver amounts to much...
