As I understand it - You earn tokens by listening to music on Celody. You can then create posts and when you do you stake some of your tokens. Other users can up or down vote your post by staking their own tokens. The amount of tokens staked up or down, and some kind of algorithm, determine whether the tokens you staked are returned to you or forfeit.
The idea is that if your argument convinces people you should be rewarded and if not, well, not. Perhaps if this runs for a while you will find that people with a lot of tokens tend to be persuasive or insightful or maybe just uncontroversial. Their "About" page specifically says that controversial views will be "slashed" (i.e. have their stakes taken).
