Regarding #4, and in particular "If it’s more of a product role, build something!"
How would that work for a non-developer?
By paying someone to do it? (not necessarily easy. Not everyone has enough entrepreneurial spirit to invest in their own idea, while still being valuable to a startup) By making mock-ups, specs and publishing them somewhere? It would seem fine to me, but I wonder if some could see that as being an "idea guy" for not having something tangible and working to show.
