There site is already in postmortem, I would have liked to seen what they had built. We learn more when we see awesome ideas that don't gain traction, it's often depressing though. I also see a trend of all these assets just vanishing. Even when sites opensource after failure, seldom anything comes up it. I will proffer the uncomfortable suggestions that the balley-hooed software practices, despite the back-patting, are not uncoupled and modular. In fact, we have reached the age of massive coupling in the full stack, even the deployment.
