Joost told me that he makes up to $10USD a month on one of his minor sites from Google AdSense, wow - I guess(?)
So as an experiment, I added AdSense ad code to the site. I didn't fill out the tax information so I won't see a dime (I don't need extra unearned income on my tax forms - I hate the marriage penalty - ugh). But I am curious to see how their statistics work. As well as how they figure out what "targeted" ads to display.
Should be educational.
