From an e-mail by a professor:
"John -- I appreciate your earnest interest in Creel and Lippmann [my link - jb]. But bombarding busy professors at the end of the semester is not in the best academic tradition, nor do we typically give feedback outside of established venues [jb emphasis] such as conferences and journal reviews, except perhaps to our closest colleagues with whom we have developed relations over many years. Rarely do I read drafts of scholarship, other than graduate student papers and dissertations, etc., so you should not feel offended
or feel singled out if folks
do not reply with suggestions for revision. I don't mean to imply this is an exclusive club, but I do think you are unrealistic to expect immediate and detailed responses to your work."
