Snapchat is expanding its Live Stories feature as part of an app update Monday to get more user-generated content into each story. The idea is that when multiple people upload content of the same real-life moment — say, the game-winning shot at a basketball game — Snapchat was typically showing just one of those videos from just one angle. Now, users can swipe on their phone screen when watching a Live Story to see different angles of the same exact moment.
