Selling Social viral landing page

Hello.

I recently finished a project for a viral landingpage. The page is similar to onwander.com/leaderboard.
Because of privacy I can't share with you the site I built.

Features:
User registration
custom shareable link
live tracking of Facebook + twitter + refferals to give users points.

Ideas:
Spread the site via adwords and then reward those who signup.
hold a competition, user with most points at the end of a certain time wins. thus increasing your viral coefficient

This is a great way to virally spread your site. (onwander received thousands of new users within hours, however this is not guaranteed to work for you)

The language is Python with django. So you need to host the site on heroku or similar companies
