I'm very curious about this.
Patrick is a PE professional pulling in 200k+ a year.
I also noticed that he recently implemented Rubicon Project, which, supposedly, helps to generate "mad cash from ads on your website". I've also noticed that the site runs slow and sluggish, with many problems (such as automatic log-out) after the Rubicon Project was implemented. I'm not complaining or anything... it's Patrick's site and he's probably paying a ton for server fees, so he's in complete right to recuperate these costs through ads. Nonetheless, I'm really curious whether one could make $50k+/yr just from ads on a modestly viewed site (according to Alexa, WSO is the 90k'th most popular site).
