Haiti allows the the donor countries to try different things like the the idea below. Think of Haiti as a clean slate albeit with all the poverty and death. To waste this opportunity to create a more efficient and effective educational program, better systems of government etc. The converse is true this maybe an opportunity for criminals to finally control a whole country not just most of its institutions.
There is more here. I am less sure about this one, largely for reasons of maintenance:
Instead of waiting for someone to build an expensive, centralized power grid, donors could think more flexibly on a smaller scale, using solar panels and LEDs to provide electricity and light cheaply, portably and quickly.
