Twitter

Nearly Named: Jitter, Twitch

Before the second most popular social network was named after a bird's call, creator Jack Dorsey was playing with two other possible names: "Jitter" and "Twitch." That's what the engineers were calling the service before its launch in 2006. The names described what happened to your phone when you receive a SMS message. After deciding that those weren't the best options, the team cracked opened the dictionary, started at Twitch and worked their way down until they landed on Twitter.
