Good idea and kind of a natural next step in the platform evolution.

But before that we need smaller steps like:

• modifing the reward distribution to author/curators
• creating incentives for good curators
• developing a smart algorithm to reward good curators based on quality, weight, relevancy, expertise, activity
  -organizing not only by tags but by categories, areas/subareas, points of interests for the users ( based on profiles), linking categories

Etc. :)
