Not to side-track from programming language semantics, but I hope to engage in a discussion on the sole entrepreneur as you mentioned.
Edit: I think the bottom line of your post and mine is that: No one does it alone. At least, that's my (perhaps more philosophical than technical) take on it. So for hackers and entrepreneurs to reach critical mass with their products/offerings, they need the input/help/support from those around them (family, friends, clients, etc).
