Has anyone out there heard about WideCircles.com. It seems like a way better service then regular pay per click. Apparently they are using refering websites ( forums, blogs, wiki, etc. ) and have a viral word of mouth distributed approach to it which is engaging rather ther then interrupting customers. My friend told me he got over 500 visits from single post which cost him around $0.40c, within a few days. I am going to give them a try today . In case you are intrested here is it.
