I always sign my email with PGP/MIME, although I do wonder if any of the recipients ever bothered to validate the signature. I mostly do it out of habit at this point. I use my GnuPG smartcard to authenticate through SSH and encrypt files so I might as well tell mutt to sign my email. These days I suspect that the average user simply trusts their provider's antispam to discard bogus emails (and as TFA points out, DKIM does effectively provide a signature, although obviously it's not the same trust model). I haven't given up on PGP, if anything I use it more than ever, but in this age of webmails and the general trend towards the centralization of the web I think the author is preaching in the desert.
