On my mathematics website, Interactive Mathematics, I have a "Comments or Questions?" feature on every page.
Some of the questions are, well, difficult to answer:
how to work out mathematics?
Others are much clearer:
What is the degree of differential equation?
Is differential equation has unique degree or not?
But most, like the one above, are totally devoid of "please". This is a free service, after all.
Some questions take quite a while to answer. It is very rare to get a thank you in reply. Lately I have been adding the following to my answer mails. Is it too cryptic, do you think?
"Manners are the lubricant of society..."
