The adsense code on it is not mine, I pasted someone else's there when I first set it up. I guess they got free money. =p
As for the boxes on the site, the smaller one is a product with an affiliation network I'm a part of, the bottom one is another adsense box. I regularly change the affiliation ad to test different offers. I made $2.50 with one of the offers recently.
