Eric created an app called Treadmill Tricorder, but it hasn't done very well sales wise. He's trying to transform it into a tool for repair people. He wants to advertise on Craigslist, but they won't allow him to post in other areas. Leo says it's Craigslist page and their rules, so there's not much he can do. This is just what they do. They also shut down a great app called PadMapper, which would map craigslist postings for apartments. Craigslist never changes or innovates, and they force others not to either. But that's their right.
