Well said, Nick
Yes, my "humor" with you is only for bantering purposes, and in turn I appreciate your sense of humor. Even though I support the H2O models for Mars, I like to play devil's advocate with you, too. It keeps the debate sharpened and honest. As an aside, I also agree with your sentiments about ignoring certain posts, even though they me cloaked in "scientific" garb. Many of these are, frankly, borderline crackpot or just plainly, if not willfully, ignorant. These days one has to save his/her wonderful biting wit and scathing humor ;-)
