It's not inappropriate for HN, but what would you contribute to this theoretical startup other than ideas?

As developers, we get pitches like this 5, 10, 20 or more times a week; I don't know too many people who are interested in jumping to work for an idea guy unless that idea guy can do sales, write code, do design, or otherwise contribute.

Hackers have lots of good ideas too, look at Google, Microsoft, Facebook, Apple, etc... All of those companies were created by hackers who happened to also be idea guys; so just having the idea is not nearly enough.

Here's a good chance for you to work on your pitching skills ;)
