My first comment is "I get it" which is great. Simple and not overly engineered. Seems like a great method for tutorials and how tos created from content experts.

I think the problem will be to engage people in creating the routes. What incentives are there to create routes? I see you get a "stamp" but is that enough? It isn't for me.

Also, is being dependent on Facebook for create routes going to hurt you? I get it that it will help this spread virally (almost required these days) but I would be interested in seeing if this prevents people from creating routes, especially since Facebook is blocked in some businesses and schools.
