Poke allows users to send expiring messages
Facebook today continued to expand the options available to users on its messaging platform, debuting Poke, a new iOS app that sends a message that automatically expires. The app allows users to set a duration time for a message, as well as to communicate with one or several friends at once. Users press and hold messages until they expire, and a timer at the top displays how much time is left on the message.
