If you could run your own money making site, what would you choose to create?

I would make a PTC but now hosted by a PTC hoster like all the new ones popping up today. I would make a unique one with jackpots, games, ads, surveys, and other creative stuff. If you don't own your own site, what would you consider creating to benefit the money making users online today? Would you be legit or scam users?
