As you may all be aware (and you all should be due to disclosure, or I have not been doing my job correctly) I work with PayPerPost to help fund this site. They have a new segmentation system that awards blogs with high traffic. I was looking on there today, and you could make as much as $1000 for a single sponsored post!
Also, PPP only charges a 35% service fee, compared to ReviewMe that charges a 100% markup. That means they are taking half you money for every post!
As I am not a high traffic blogger, I still love PPP. I is a great service for all bloggers. As disclosure is required, I feel comfortable working with them, because you know when I am engaging in blog marketing and when I am not.
