It's a classic Web 2.0 strategy: 1. Locate an activity that's free, that anyone can perform sitting at a computer. 2. Turn (1) into a product and sell it back to people who don't realize it's free.

To do this, I need to sit down at a computer that already has Python installed, lying dormant, waiting to be used. This outfit is betting that people are unbelievably stupid. Maybe they're right.
