Currently all funds given go straight to the creator - 'keep it all' model.
With this model it is a bit harder to get funding due to the problem of trust. The way we plan to tackle it is by allowing creators to do long-running projects, write entries/articles that can allow them to grow their trust through time.
That said, we'll also be experimenting with the 'all or nothing' model and will be launching something in the coming months related to that.
