A story about instagram getting 500 users turned into something more interesting.
People noticed that Zuckerberg put a piece of tape over his webcam and loudspeakers at what looks like his desk at work. Seems like this is something people do regularly to prevent unauthorised / accidental access. It’s probably overly paranoid but no harm in doing it. I can’t remember the last time I used the camera, probably to skype when I was still in London.
Anyway, put a tape over your camera, cover your hand when typing in atm pin, lock your doors, check your windows at night. It’s all good practice.
