Earlier this month, Facebook announced it would be using facial recognition to let users know every time a photo of them had been uploaded to the site. Such a feature would be extremely useful to one man - publicrelations professional Jonathan Hirshon, who has managed to _______ for the past 20 years. He has more than 3,000 friends on Facebook and regularly updates his profile with personal information - where he is going on holiday, what he has cooked for dinner and the state of his health.
