##Badge Type
Good: Badge is plastic envelope with paper inside, has cord attachments on both corners to not flip, and is printed on both sides.
Better: Badge is a preprinted, recycleable plastic card printed on both sides (ala DockerCon).
Best: Badge is a little booklet with the summary conference schedule inside. Printed/stickered on both covers with my information.
Fun Alternative: no badges, only name stickers (PyDX).
