Brad,
Mainstream does very well for alot of us. I wouldn't give up adult that quick, just diversify your basket a bit.
I think you used to do hosting, etc, etc I get offers all the time for hostingforums.com, don't want to sell, but want to get a site up there. Forums, Reviews, etc. I bet it can make some good coin after awhile...
Let's talk about it. To be ohnest I don't have alot of time to put into new stuff, at least until spring but a person with the get go like you could do well
thanks
Todd
