Jeremy notes "One might conclude that the traffic equals money, which is generally true."

I guess I'd have to agree with that myself given the places I have AdSense plastered about.

Podfeeder takes the lion's share by far (which also has the most GB/mon bandwidth), followed pretty much in order by newsrecall, and shrinkr

I'd also like to point out that "lion's share" is all very relative. I still have my day job.

From looking at my stuff I could probably quote a fairly general equation that would be $$/GB-of-relevant-bandwidth but that may or may not get me in conflict with the AdSense EULA.
