I found this fascinating quote today:
Ok, here we are reviewing another affiliate/traffic rotation program. This one I will give a thumbs up, though! It actually works. Super easy, you view sites, you earn credits or money (your choice), then you can cash that money in for your site being posted. Does it work? yes. Can you really cash the money in for CASH? Yes. There is a minimum withdrawl amount you have to reach before you can actually have the money transferred, though. It is about a penny a click, so it will take a while. But, you can do like I do, view a few sites, take those credits and convert them into your own advertisements.Mommy Tyme, Mishaps of Mommy, Jan 2010
