Hooray! It's a special year-end Ask Me Anthing Day!
(You can still ask me anything; it's just special because it's the end of the year.)
Send your questions as comments to this post, or by email to firstname.lastname@example.org (let me know if you want to remain anonymous), and I'll do my best to answer in posts throughout the day.
And thanks for all your questions, comments, and silent readership throughout a jam-packed 2012!
