I was thinking something similar - these days really valuable contents seem to resurface from a few years back. Two days ago I was reading a blog post from 2012 which I though was worthwhile. Walden's Thoreau states that 'Books are the treasured wealth of the world and the fit inheritance of generations and nations.'

=> I believe that we are lacking the commitment that one had to put into a project such intent as a book then with the current fastfood social medial / article generation. I also believe that in its place, a hybrid of sorts will come and surface softly back multiple time to underline the impact it left on the collective unconscious. This sounds like what we're seeing.
