And from another exasperated Facebooker:
This morning my mother was complaining that many of the e-mail addresses in her Droid Razr contacts had been replaced with Facebook ones. It would seem the Facebook app had been populating her address book with e-mails and contact photos, and decided to migrate all her Facebook-using contacts over to this convenient new system. That seems like a much greater controversy to me than Facebook hiding people's e-mail addresses.
I recently updated my iPhone to iOS 6 beta, which has Facebook integration. Since Facebook changed the email addresses on contacts, I've actually lost every single one of my email addresses including those for work. Emails to my boss have gone unanswered as they've been going to his Facebook! Driven me insane and absolutely horrid move for Facebook. Very much regretting wishing for this whole Facebook integration thing now!The complaints go on and on. So yeah, now might be a good time to see if your boss got those messages that you won't be coming into work.
