Well, in the two weeks or so that I had the AdSense ads on the site, my income averaged about $0.18 per day. In all, I raked in a monstrous $2.73. They don't even send you a check until you reach $100, so at this rate, I'd have to wait a year and a half to actually receive any money from this. Yeah, so the ads are gone. I guess I made some invalid assumptions when estimating the number of ad impressions I'd get. Ah well, it's good to know I won't ever again have to struggle with the moral dilemma regarding whether or not it's worth putting ads on the site. Now it is answered definitively in the negative.
