I wasn't around when the meta on the main trilogy was formed, but meta we down vote things we don't want to see. It's like a caucus or straw vote. If I raise a controversial issue and everyone disagrees - the downvotes shouldn't take away from my reputation on the main site and you don't really earn reputation here to participate - you earn reputation on the main site to qualify to ask and answer here.
Why are these badges here:
Mortarboard - Earn 200 reputation in a single day
Epic - Earn 200 reputation 50 times
Legendary - Earn 200 reputation 150 times
Badges are separate on Meta so why are these here?
