Spn fic help?

[wesleysgirl]

So, I realized this morning that part of the problem with scanning the Spn newsletter for names I recognize is that it's not a particularly helpful method of identifying stories I should read when I am unfamiliar with the vast majority of Spn writers.

Therefore, a question: Who are the big name writers in Spn fandom? Which writers are producing a fair amount of quality fic? Help me, oh flist!
