What would I do with sex.com? The possibilities are endless.
1. IF I followed the PPC model that is currently in place I'd also start up TGP.SEX.COM. The better traffic from the TGP would filter into the PPC area.
2. Or I'd look into making endless pay sites:
teen.sex.com
plumpers.sex.com
bbw.sex.com
mature.sex.com
gofuckyourself.sex.com
tranny.sex.com
gay.sex.com
etc...
3. A combination of all these might even work with the right design and marketing.
4. Sell the domain name for multiple millions.
