It's on an O'Reilly blog, so it must be true: Facebook has lost some users' email settings . The company had to send them an apology, and a request to reset things. Let me explain in sysadmin jargon: That's fucked. Not because Facebook's engineers failed at Backups 101, but because by now the Marketing department has figured out they can reset all our email preferences to "Spam Me Like Crazy" by pretending to lose them again in January. Laugh while it's still funny.
