We do not use any third-party ad providers. We have worked hard to think of a less obtrusive way to fund the site without getting in the way of your browsing experience. Our ads are simple affiliate links displaying just images and text, originating solely from our server. Also, our ads have to do with what's on the page, not you. This means that we're not putting you through a gauntlet of ad brokers utilizing creepy and cumbersome tracking mechanisms. We are continually working to make these products more relevant without affecting your enjoyment of the site. Thanks!
