I removed AdSense from Something More. It was a very informative experiment, but AdSense doesn't match my content as well as I'd like and it brings in zero revenue. Amazon, on the other hand, actually produces referral traffic, but no revenue (as of yet). As long as people click on the ads, I'll keep it up. Not because of the revenue potential, but instead because as long as people willingly follow the content-matched ads, Amazon's providing a service to my audience.
