Seems being paid to post about things can make you money - directly from the comapny looking for links and good PR.
They want you to make money - hell it is how they make their money too. Don't think the affiliate program or referral program they offer is questionable. They have some serious deep pockets and may be able to use this to get themselves inexpensive links and PR.
I am signing up and will see what can be done with this... will be interesting to see if they rise in the SERPs and get others to buy the system.
