How do I make my rails site a business

I'm currently coding day and night hoping to make something out of my web project. Once I'm done with it, what would be the next step? Google ads? At first I wasn't even thinking about "business" but now I see that It can be. Once I'm done with the app, I'll be sure to mention it on here. Basically, I'm just asking for some ideas on site promotion, how do you guys and gals do it? -FDS

Maybe this is better asked on quora [1] or some other [2] startup discussion site? Not really a rails question, per se.
