ReviewMe

If you have not heard of ReviewMe.com, you are living under a rock. ReviewMe is currently the smartest way to advertise on the net, as well as to make money as a blogger. For instance, last month, John Chow has made $4500 from ReviewMe.com.

Now, if you take a close look at John's blog and browse through ReviewMe reviews, you'll find out that a good deal of these reviews were written by Michael Kwan and not John Chow (this does not violate ReviewMe TOS in any way, it's perfectly OK).
