A few months ago, we did a short video on YouTube that covered Google AdSense tips:

It may be due to my doubled traffic and a digg frontpage hit, but your suggestions on ad optimization tripled my income on AdSense. It’s still not a lot of money, but it’s three times a little amount of money which is good.

Digg users seldom bring with them an increase in AdSense revenue for quite a few reasons: (a) they’re largely underage, (b) they’re largely idiots, (c) they’re largely underage idiots, (d) they block ads in their browsers, (e) they hold no staying power in terms of your audience, (f) they have attention spans shorter than a nanometer, and (g) they’re quite predictable.

Digg has power because it drives traffic, not because it drives intelligence.
