"I can only imagine what it's like to work in a large-scale IT operation in the porn industry ;)"
I've heard it's about the most unsexy thing ever. The technical aspects are all about shipping massive quantities of data cheaply and reliably. The, erm, video-production aspects are about presenting a picture that will satisfy customers and leave them coming back for more.
In other words, it's pretty much like Google or any other big-data startup (and there're employees at Google who used to work in the porn industry). Not having been a part of it, I don't know what the culture is like, but I've heard it's pretty much all business, and they have significantly less fun than we do at Google.
