In a failed attempt to clean spam from the comments, we've lost all of the comments posted since late last year. Sorry.
I've often debated whether or not I should post some of my more in-depth responses to your questions in the comments section or as a primary blog post. I guess I have my answer now.
I should also take this moment to recommend that if you've got a blog, that you post any siginificant response commentary there and trackback rather than posting to the comments section.
With all this comment spam, comments may eventually go away. We'll see.
