I would get ads on it right away - money is always nice. I would also use it to send traffic to my other sites and my twitter account.

Start pitching it to news sites and the like, because there's a very high chance it'll turn into something bigger than just something to scratch an itch. Create a Facebook page; start gaining fans. Same with Twitter. Increase the presence of your site.

Very cool product, good luck! You can always email me if you need help. :)
