One of the things I love about local and the Web in general are the crazy niches you can go after like Find a Mohel. I was checking out the profile of one of my Twitter followers @jwegener and found this great service he created with his sister, ExitStrategyNYC. The concept behind it is pretty simple, it tells you where the best place is to stand on a subway car to have the most efficient exit from the platform.
When I lived in NYC I was pretty proud of my ability to pick the right place to stand on the subway. Now everyone can feel that power that previously took years of hard-fought experience.
Of course as this thing becomes more popular, it will become self-defeating as it will become harder and harder to get close to the right door. But such is the fun of local.
