Decay gazing (ruin porn, if you will) has become a cottage industry in my home town of Detroit. In some sense, it's at least partly responsible for the economic turnaround that downtown is currently experiencing. All the hipster urban spelunkers wrote blogs, which made all the coolest kids from Brooklyn move to town (so to speak; the people here obviously come from all over), and now we have a viable business district and home prices are rising quickly. It's a strange cycle. People flee, a once great place is turned to ruin, and then nostalgia gives it life once again.
