Hah, the way you phrase that makes me wonder what you found.

Right now really just web apps. Content sites are doable, and I know people running networks, but it's not possible to do profitably without clickbaiting, low-quality mass-produced content, and other greyhat techniques I don't particularly like.

I think it's fair to show you an ad if I save you 30 seconds to a minute of time. Creating garbage content slideshows with writers from the 3rd world countries to rack up pageviews is one step over the line for me...

Simple apps are great because they have utility (so google always approves your tag), and honestly the doubleclick exchange isn't so bad -- with enough simple single-page apps, it accrues pretty quickly.
