Note from JWR:

I get more than 40 e-mails a day, more than half of which include specific questions. My humble apologies for not being able to respond to every e-mail. For those of you that do get replies, my further apologies for being so terse. You might feel cheated when you get just a two or three line reply to a 20 or 30 line e-mail. But if I were verbose as I’d like to be in my responses, I would only be able to respond to a small fraction of the e-mails instead of half of them. Since I have a full time job as a technical writer I only have about three hours a day (evenings and early mornings) to respond to e-mails and to put together the blog. Many thanks for your understanding of my situation!
