I have just deleted all but the most recent two weeks' worth of emails in my in-box. As usual, I had fallen so far behind on answering questions that there was no chance I could ever catch up. So if you had sent me a question earlier that you are desperate for an answer to, please re-submit it. Otherwise, my apologies for never getting to you.
(That said, I don't think I'll ever be able to answer everything I receive, not without quitting my job and blogging full-time, which seems unlikely. But questions that have the best chance of getting answered generally fit more than one of the following categories: short, interesting, well-written, infuriating in some way, and/or things that I haven't answered before.)
