Right on. I went to a hackathon as a facilitator/judge type. There were 3 idea guys for every dev. The devs centered on some good ideas or brought their own. There were several idea guys that left feeling like their billion dollar idea was just missing a code monkey cog to slide into the code monkey cog slot to make it happen.

One of them had come up with oink aka foursquare aka yelp aka gowolla ...

Sad really.
