AdSense Can Sense My Soul

I’ve had friends ask why I have advertising on my site; After all, it’s not like I’m gonna pay the rent with the kind of traffic that a Snoop Dogg fansite drives. Usually, I explain that I just like to understand how that stuff works, to keep up to date with the customers I deal with at work, or just because of curiosity.
But today, I have a much better answer. It’s because sometimes that little bit of Google code can make something magical happen.
