2. What is #PGP, the "reason for the season, so to speak"

PGP (which stands for "pretty good privacy) is an ancient, arcane, poorly-documented and questionably-coded, hard-to-use piece of software with bad defaults.  

BUT, can also:
 * encrypt messages so that only recipients can read them, without having to first share a secret key or passphrase
* Encrypt files on-disk so that only you or the recipient can decrypt them. 
* Causes ass-hemmoraghing in people that hate PGP and want it to die, including but not limited to: the federal government, your country's government, the NSA, the CIA, your local police, and oversensitive infosec experts (who are technically right, but lol.)
* GIVES YOU VALUABLE NERD CRED
