Sorry to hijack but I have always wondered this question myself I am a developer just a newbie one. I've always wanted to attend a startup weekend I know enough to be dangerous and I do work as a freelance front end dev but I am certainly no CS major ninja programmer. Would I look like a fool if I attended a startup weekend?
