So in light of the comments in the post below, I've decided to put my money where my mouth (er... fingers) is (er... are) and have signed up for an AdSense account to see just how the future of revenue streams on the Internet works. (I recognize and accept that that last sentence made me sound like your great aunt who just signed up for "the hotmail.")
So far, the sign-up server was down for an hour and a half and, after signing up, it takes one to three days to have your site approved, neither of which seem particularly cutting-edge or user-savvy, so I'm going to chalk one up into the skeptical column for now.
I don't expect to make any money off this site, by the way, this is more for the experiment/learning experience of actually serving these ads than it is the ¢72 that I stand to make from it. Because while I, like Whitney, firmly believe that children are our future, the rest of the world seems to point to Google instead.
