Truly, finding suitable people to handle this role as in the case of the crypto academy will be very difficult. I now understand better why the team can not do much about other community management.

It would be interesting to know what people would think about having more centrally controlled communities

From the above, i believe a lot of people will buy the idea because it will be quite transparent, free and fair. No one will have to power down the entire labour of the users for himself alone. It would be in such a way that the resource will be use solely to support all those posting in the community. A certain % can be set optionally to help grow the community account.
