As a Program Owner/Sponser it's differant for me. I have 30+ paysites and a whole network of sites and affiliates to deal with so Adult is pretty much what I do full-time.
I do have a couple mainstream websites I started before getting into Adult in 2008 but those are doing only so-so because I don't pay attention to them much.
I am always looking for mainstream opportunities tho since it's never a good idea to have all your eggs in one basket.
