		<description>Has anyone out there heard about WideCircles.com. It seems like a way better service then wasting money on PPC. Apparently they are using refering websites ( forums, blogs, wiki, etc. ) and have a viral word of mouth distributed approach to it. My friend told me he got around 100 visits from single post which cost him $0.40c. I am going to give them a try today . In case you are intrested here is it. http://widecircles.com?s=imt1</description>

		<description>Fifth grade math does not an analysis make. While the approach is good, the mathematical/statistical analysis is pathetic. Hint: What is the probability that such a difference in distribution is random? How should the sample sizes be to be confident about these number? 

This is coffee table mathematics that good only for impressing people who do not have a background in sciences and how to collect and analyze data and draw conclusions. But its still much better than what most people do.</description>

		<description>Kevin,

Were the ads only placed on google&#039;s search page?  What about google ads on blogs and such?  Or in domain only searches?  If ads are on the other two - you may have the answer.  No, ads for Firefox on the search term Firefox on the google page don&#039;t help but you do gain people on google ads on blogs.  

I&#039;m assuming you limited the ads to the google search page but I didn&#039;t see that posted anywhere.</description>
