I wonder if the mail tracking data is sold to credit reporting agencies. Oh look he got an old fashioned paper bill from his water utility, and then he replied with a letter (payment) from the mailbox across the street exactly 3 days later. How fascinating and presumably useful as a metric, somehow. Marketing agencies would likely be interested. Oh look he's exchanging correspondence with a known estate lawyer, someone must have died, how can we profit off that? I suppose interesting environmental studies could be possible, since at least 90% of my incoming paper mail is garbage. Big Brother doesn't throw away things very often, all CYA you know. I bet a century from now looking at the social network of old fashioned paper Christmas Cards would be interesting genealogy research. (edited to add: Mothers day cards!)
