After you do your taxes on paper, do you put them in the postal box for the USPS to pick up? Do you also send other paper mail? USPS has this great service called Informed Delivery that gives customers scanned images of all our mail. In fact, USPS has been scanning, OCRing and electronically processing mail for a long, long time. I would say that their elaborate surveillance capabilities are on a par with Google's in some respects. They absolutely have social graphs available for anyone who corresponds with anyone else through the mails. Not to mention the rampant mail theft that's being reported these days; I'd say that email has gained an edge and is safer in most aspects than putting it all on paper, unless you're going to walk it into the IRS on foot.
