exactly this is why i wrote above my comment....i dont know how it will be implemented in a way to let people be stimulated in doing contributions.....maybe as stated "Contributions are only eligible for the voting round 48 hours after submission, for them to gather enough scores from the community." the community will have also the power to give some judgement on the work and give a score in order to make it less centralaized on moderators. if this is not the case then only mods will get the highest scores as they will abuse their power and give a boost to their contributions.
