Through several metrics we continuously measure we determine reliability of users. So, empathetic and positive users that are constantly providing good answers receive a higher score and in the contrary the opposite is true. The higher the score the more questions the user gets assigned and the more he earns per response. People that are better qualified thrive and people that are not fall behind on this meritocratic system where users have to earn their place.

The person that upvotes the answer is the person that asked the question. So, if it is useful for that person the purpose was served.
