Yeah, that's what we're building at the moment - some way of getting people interested and working together. It's tricky, and one of the directions we're looking into is for the website to be a way of finding people in your area. It's a lot more about creating community, and getting people talking to one another, and personally accomplishing something, than the actual finished product - at least, that's my take on it.
At the same time, I think a month is enough time to get a basic app built on your own. That's why it made sense to do it for an entire month - while it's not easy, it's still a challenge.
