It would be great if someone ranked the listed tools somehow by references on HN, StackOverflow, etc, linked to posts/comments/questions according to votes. So much great information flows through HN but it's hard to random-access that information easily when making design decisions.
Open source entrepreneurship would be creating a capitalistic enterprise in which anyone can freely participate, and whose participants can modify its practices for his/her own use, with an end goal of monetary profit. Something like:
-- a pool of capital from which anyone can borrow for entrepreneurial purposes and pay back with zero or minimal interest.
-- an enterprise with a stated function or goal that anyone can join and from which anyone can profit.
This is just a collection of links with a sexy header.
An interesting question would be: can you open-source entrepreneurship and retain the core principles of both?
