Fortnite’s monetization model is based on cosmetics: The skin your character wears; the looks of your glider and the tools you use; the way your character dances (emotes) – all of these are signaling amplifiers with different signal messages to uniquely express yourself in the game.

At what point does payment occur, and are you concerned with the possible perception that this is pay-to-publish? Payment occurs as soon as you post your paper online. I am not overly concerned with the perception that this is pay-to-publish because it is. What makes The Winnower different is the price we charge. Our price is much much lower than what other journals charge and we are clear as to what its use will be: the sustainability and growth of the website. arXiv, a site we are very much modeled after does not charge anything for their preprint service but I would argue their sustainability based on grants is questionable. We believe that authors should buy into this system and we think that the price we will charge is more than fair. Ultimately, if a critical mass is reached in The Winnower and other revenue sources can be generated than we would love to make publishing free but at this moment it is not possible.
