Are you an author or author-to-be? Do you have a pressing question about book publishing? Write to Booklab, and I'll answer for free if your question is selected, and if you agree to have it posted on the blog. It's all anonymous unless you wish to be identified. Booklab does charge for classes and professional literary advising, so this is a great way to communicate gratis. Maybe it will turn into a column!
HINT: To really keep it anonymous, post your question as an unsigned reply to any blog entry.
