In his book “never eat alone – and other secrets to success, one relationship at a time.” Keith Ferrazzi mentions that he pings constantly. What is pinging?
I know pinging from a submarine, “a high-pitched or ultrasonic sound whose echoes provide information about nearby objects and vessels”. Then there is a ping for a network, “which a remote host is expected to echo, thus indicating its presence.”
When you had/have a BlackBerry you may know “ping” as a free chat function with other BlackBerry phones.
