Sounds like an awesome idea. But the only thing about this is that many people don't like to lose money. And with stock exchanges, your stock can either raise or drop... and people will fear the fact that the stocks may drop and they will lose their whole $5, lol.

Will the stocks be based on stocks from like NYSE and NASDAQ? I'm guessing you guys might have some amazing coder in the background over there that's going to find a secret link that updates the stocks stats every 23 minutes, lol. Ya.. I bet that will happen.

Anyway, sounds like an awesome idea. It should draw a lot of people to the site. Little thing I learned through my few years of designing... Where there is money, people will come. Enough said, lol.
