There has been a wind blowing lately through the adult community that seems to be moving a lot of adult webfolks toward more mainstream projects. I can tell you that my ROI for mainstream has been a lot more than that for adult. I think that many others will agree.
If you would like to try your hand at mainstrem I have assembled a list of programs that are doing very well for me.
