Two questions regarding your proposed structure of the Board Members.
Can users from a continent, in your proposal, vote for a person who is not from their continent for the Board seat?
Enough Steem users can be considered in a way 'nomads', but still have an important voice in the community. If one of them would run for a Board seat and be elected, which continent do they represent? Say for example, they have one citizenship (or more), a residence across the globe and rarely stays in one place more than a month.
