The risks and rewards
This is a really good article looking at the business side of space. The writer notes that a lot of the commercial effort so far hasn't attracted public notice, but the SpaceX Dragon success is changing that. The article goes on to explain that space is potentially a high-reward arena of business, but we know it's high-risk, especially when human flight is involved. The entrepreneurs are moving ahead nonetheless.
(I think there is a typo in this sentence: "SpaceX founder Elon Musk, for example, has said he envisions developing aircraft to take people to Mars." Aircraft, really?)
