Would you compete in making money online? I recently started up this site called CashChallenge.net. It has competitions that anyone can join and you compete to see who can make the most money online. I give you a step-by-step method to make money and you to have use that method to make as much money as possible in a certain time frame.
Quickly read over your idea and rules on your site. I like the idea of a challenge (whereby over a year you try to make as much money as possible, winner get a % of the money everyone else made), but your challenges are too short a time frame and don't promote good websites. Also over a short period its more luck than anything that you make money. [Edit] In addition if a site took off, then I wouldn't want to spend the extra time setting up for each of your new 'challenges', I'd be too busy trying to make money.
Actually the time frames aren't too short. I got this idea from 2 people who did this and both made over $120 in 48 hours.
