Developers have their pick of non-technical co-founders. It's a lot harder to approach someone with just "an idea." What are you offering in return? How do you contribute to a startup in those initial months? Sure, I've read plenty of posts on what non-technical co-founders can do in a startup - lots! But, it pales in comparison to the bread and butter of a startup: building a product.
If you're looking to build the next Google or Wolfram Mathematica, find an expert or 2.
The guys at SeatGeek built their initial product - a crude prototype but decent enough to promote at TechCrunch. Now, they're funded and growing. They were not programmers, but they needed something and they didn't have the resources to find someone to build it. Coding is a bottleneck for a lot of non-technical folks. Do what you got to do to get through it, scotch tape and all.
