Alright, looking at this again, my favorite candidates are 1, 2, and 5. I find myself agreeing with Ed for the most part.
The only thing that makes me slightly nervous about letting number two into the staff is the fact that is new and may drift off and become inactive. Who knows how long his gusto will last. But I do think he is a good candidate, even though he is new, a new face, new ideas, not someone who takes himself to seriously. He also visits all the forums, epically GC so that is another plus in my book. Hopefully if we make him a CK he will start taking the responsibility a bit more seriously and stop spamming so much.
