ECOSOC is one of the principal and most known organs of the UN; it consists of only 54 members at a time; and works according to clear and predictable rules of procedure, including adopting regular resolutions.

As it grants consultative status to countless NGOs around the world, it is probably the most "approachable" UN body, the closest one to ordinary individuals.
