How come responses to discussions are posted last not first

i dont know why they display the latest responses on the last page, do you?

how much money on average do u make here,

how many points or posts, that number next to your name equivalent to how much money

will people just respond just to make money, and is it legit

do people really give honest oppions or do they just want money, and does this site really pay you or is it a fraud
