There's apparantly just under 33,000 of us, which is about the population of my town, so space wouldn't be an issue. There would be a special island for all the people who have registered here and never posted anything, and another for people who refuse to spell and use grammer. Both islands would then be nuked, or something similer. All the famous racing tracks of the world would be on the planet. Cars would be plentiful, as would electricity, food and petrol. The day would be 26 hours long, the summer would last for about 6 months and the weather would be sterotypical Florida weather (hot and sunny).
Then some sort of plague would come along and wipe us all out, except for Famine, with his amazing science skills, would build a rocket out of tree bark of something and go and live on the moon.
