The key with CK is that not only he is a really committed evaluator, but he is an exceptional writer. By that, I am not referring to grammar and constructing a sentence. I mean that he really articulates his ideas well. (And quickly, too. I have sometimes exchanged posts on here with him. I write something, check back 10 minutes later and he has a 1000 word post ready, exceptionally written, and I am like, "how is that mathematically possible?" LOL.
