Yeah, the prizes are paid for out of pocket by me. It's not the most expensive project in the world, let's say I average $50/day ($1,500/month) in gift card costs and $10/month on a server. I live in a 42 square foot room and share an apartment with 5 people, so I'd say that the expenses are taken care of from my choice of a frugal lifestyle (we're talking Manhattan, New York rent here). Those are my only expenses to run and maintain the site. The risk of $1,500/month for a couple of months to possibly achieve my dream is a no-brainer.

My goal is growth. Craigslist is a great example of a site that I want to be like. Offer an awesome service for free. I'd like to have companies fund the giveaways or maybe even have companies pay to have their giveaways featured as a top result. I don't really know yet. I'm sure there's some win-win situation that I haven't thought of where the users get awesome free stuff and there's a way for me to work on the website full time.
