Big Names in the WW fandom

I was just browsing through blogs and found that people had created quizzes telling you which Smallville Big Name Writer etc, you were. And I thought, gee that would be cool for West Wing.

Then I realised, I've never had a real discussion about who the big names are in the West Wing universe. I have some opinions, and my own favourite writers, but have never run across a discussion about it.

So, any West Wingers reading my live journal (Okay, mandysbitch )- let me know, join in the conversation. Who are our big names?
