Sites like WorldSex, Thumbzilla, Hun etc are too much work to maintain. Sites like Excite, Google, Altavista are WAAAY too much work, even in a team...
I'd like a shot at PinkWorld.com, but only because I want to know how much money he is making from paid submissions.
It also would be nice to say that I was the webmaster of a site that makes me look like I could stomach anything - fetishhotel.com, sicpics.com, hardcorehospital.com, bizar.com, etc
