Really? Well my curiosity is peaked - I look forward to reading your chapter about this. I'm always looking to learn something new. :) I have an article about this subject that I think you may find interesting (I'd also love to hear your thoughts about it) I'm not sure if I should post it here or email it to you - it's kind of long. Let me know if you would be interested in taking a look at it and if so, where I should post/email it.
