In some countries the money that a Hero member earns from posting monthly on this forum can be a lot of money, enough for the basic living. It will depend on witch country do you live, and what services you think that are basic for your level of live.
A hero member can get 0.4$ per post. If he posts 200 per month, he can earn $80 per months. But the quality could be low.
Where you can live of $80 per month? Maybe somewhere in underdeveloped countries but for most of the world, this is not enough.
