Mainstream is a completely different animal than adult....
Income wise, most mainstream "affiliate" type programs (CJ, Amazon, etc.) are laughable to the adult webmaster.
Stand alone type programs (cellular phones, insurance leads, etc.) generally require targetted traffic to work well...if you just throw up a page of mainstrearm programs you are going to be sorely dissapointed...
The good $$$ and good demand right now are for pop window inventory. We handle about 19mm mainstream pops/day and we are 100% sold out and have been for months. I've been in mainstream since 98 and it's the first time I've seen pricing for an ad method increase.
If you have mainstream pop windows, I'm buying.
