In building Reddit, a community of thousands of discussion threads, into one of the most frequently visited sites in the world, Huffman has grown aware of the way that technology alters our relations with one another, for better and for worse. He has witnessed how social media can magnify public fear. “It’s easier for people to panic when they’re together,” he said, pointing out that “the Internet has made it easier for people to be together,” yet it also alerts people to emerging risks. Long before the financial crisis became front-page news, early signs appeared in user comments on Reddit. “People were starting to whisper about mortgages. They were worried about student debt. They were worried about debt in general. There was a lot of, ‘This is too good to be true. This doesn’t smell right.’ ” He added, “There’s probably some false positives in there as well, but, in general, I think we’re a pretty good gauge of public sentiment.

The increased inflation rate in the 1960s, the US monetary devaluation, the continued concern over a possible nuclear exchange between the US and the Soviet Union, and perceived increasing vulnerability of urban centers to supply shortages and other systems failures caused a number of primarily conservative and libertarian thinkers to promote individual preparations. Harry Browne began offering seminars on how to survive a monetary collapse in 1967, with Don Stephens (an architect) providing input on how to build and equip a remote survival retreat. He gave a copy of his original Retreater's Bibliography to each seminar participant.[citation needed]
