True or False?
The object is to predict something about the person who posts below you. That person starts by answering "true" or "false" to your prediction, followed by making one of their own. It is what I refer to as a "posting" contest.
EXAMPLE: Bob: The person below me dyes their hair...
Anne: FALSE !!! The person below me LOVES broccoli...
Jeff: false. The person below me dyes their hair...
and so on and so on, until a specified date. Pick winner(s) by random draw.
