Beepers, as they’re also known, introduced millions of people to ringtones and vibration notifications, and were commonly seen clipped to belts and purses in offices and high schools around the world.

The pithy statement encapsulates the enjoyable side of Internet anonymity – but says nothing about its dangers.
