Stop fighting the urge to share an embarrassing selfie with your friends for fear it will end up public: with Snapchat, you can send any picture instantly to another user and set the amount of time, from one to ten seconds, that the photo is visible. After that time limit is up, the picture is erased forever. The person who sent the picture is alerted if the receiver tries to take a screenshot, so no worries about any photos ending up on Facebook or Twitter.
