>....otherwise, the chance of a referral making that much is too slim.

Don't say that, in my case it was close. I started using AdSense and two weeks (?) later the referral program was initiated. Given that I get most of my Google news from you (including the one about that program) I would have used you as the referer. I made those 100 dollars in less then 90 days. Given your audience with this blog it's not that unlikely this will happen with other people.
