Yeah the sponsor ads are great. They're hyper focused on my interest while they know nothing about me when I visit the website. Golly I wish how they would do it! Sometimes I get to know iOS development related products that I didn't know about but should have. Think they had about the same click-through rate as all of the other banners I've seen last year combined.

On the other hand Google seems to think I need a Foreverspin after carefully analyzing all of my click behavior over thousands of websites.
