Right! And give me a free iPod as well!

I'm a curious guy, so me and a friend sign up for this BS. He got one. I was blown away. It's a matter of shameless self promotion.
The website above explains some things about it. I wrote it because I had the same questions. Keep in mind while you're reading it that it's marketing-speak. Factual, but sickeningly positive.
Is it worth all the trouble and effort? I doubt it, really. I ended up just buying one (see previous posts regarding Amazon rant...) However, I was glad to learn how it all worked.
Bottom line, it can work, but you have to be willing to be a shameless shill. The company involved makes money because many, many people try, but most give up before they qualify for a free product.
