PayPerPost – selling out your blog?

Michael Arington just spoke about https://payperpost.com/, a site where you can sign-up to get paid by companies to blog about their products. They set up a bunch of parameters for each deal and then you have to keep the post up for 30 days. You get compensated through PayPal at the end of the 30 days for each post. Would you do this? Are we selling out our blogs?
