I never really understood how snapchat works. I don't know anyone on it, how do I add people? The only snaps I got were from the Snapchat Team itself.
- Add people by username: celebrities often post their username on other social networks, you can find aggregate lists
- Add people by "snapcode": hold the camera over someone else's phone while they display their snapcode, your snapcode is the yellow QR code thing you see when you swipe down from the main screen
