#mobile sharing.

Following SnapChat´s fun & self-destructing messaging app, Facebook just launched a similare app for iOS, named Facebook Poke. Users can poke or send a message, photo, or video to Facebook friends to share what they're up to in a lightweight way. Each message expires after a specific time you've set, either 1, 3, 5 or 10 seconds, and cannot be retrieved by either party again. When time runs out, the message disappears from the app. Users can poke an individual friend or several at once.
