I have earlier analysed just how much information (or ethnicities, languages etc.) that got lost in the Fall [*]. But all hope might not be lost for apparently deleted information: http://www.technologyreview.com/view/519391/internet-archaeologists-reco... http://arxiv.org/abs/1309.2648 Since I have been thinking about an adventure set among a community of information archeologists, this paper was rather welcome. What about thinking up interesting adventures, problems and communities among the people resurrecting the lost information? No doubt plenty of Argonauts and classic academics (Oxford-Shackleton is likely crammed with them) are doing it. But there are also hobbyists and freelancers: my adventure The Black Spot involves a freelance data archaeologist (alias, a data junk dealer). In my THS module I suggested that there are some people who buy up files from estates and then mine them for valuable information. The reconstructivists are interested in putting it into bigger structures where individually pointless pieces of data reveal useful things. And no doubt many companies do this for sheer profit. There are obvious risks with old caches containing viruses and nasties from the Fall, but also sensitive information certain parties want to see buried. But there are many other kinds of information hazards - can we come up with a few less standard examples? *: To repeat, since I can't seem to find the original posts: If there are N copies of something (speakers of a language, copies of a file) and they have independent probability p of surviving, the chance that at least one copy survives is P(N)=1-(1-p)^N. If p=1%, then P(1)=1%, P(10)=9.5%, P(100)=63%, P(1000)=99.99%.
