I find your reaction fascinating. You find the topic of porn so disturbing that a mere (very dry) discussion of its business side ruins the entire experience of HN for you?

On a side note, you may be naif about hacker culture. On one hand, a lot of hackers consume porn (by virtue of the fact that a large percentage of the general population does). On the other, we tend to be curious about stuff, even stuff that is considered a "poor subject" by conventional social norms. We're not that big on conventional social norms...
