The awesome thing about holman, is that he did this app just for fun and the love of "the hack". In my opinion he will gain much more than a chunk of ad revenue. A very well-respected reputation. This to me seems much more valuable than even $5k ad revenue. I don't feel like we would be talking about him near as much if facelette.com was some spammy looking "made for adwords" app.
When you go to the site it is just so pure and honest, it doesn't make you question what you are doing, or who is doing what with your information.
