J.K. Rowling took to Twitter on Tuesday to not only explain the reasoning behind the scoring system for Quidditch in the
Harry Potter saga, but also how it can be seen as a metaphor for the human condition. That can be found here.

J.K. Rowling: It makes total sense. There's glamour in chasing an elusive lucky break, but teamwork and persistence can still win the day. Everyone's vulnerable to blows of fate and obstructive people, and success means rising above them. Quidditch is the human condition. You're welcome.
