"I'm particularly interested in introductions for non-experts to subjects like biology, physics and astronomy, but I thought that opening up the question as broadly as possible would make it most interesting to me and other readers, especially as a future reference-point. I am thinking of books like "Mathematics for the Million", which made math accessible to a great deal of people."

Joho: "Where can I get a free blog?" got 664 results. " "How do I tune up a bicycle?" got 11 hits. Where can I get vegetarian omega 3?" pulled up three answers, all pretty relevant. "Should I reply to spam?" got 372 hits, some generic and some specific to particular mail programs or sites. "Does putting in a new hard drive invalidate the warranty on my thinkpad" and "What's a normal triglycerides result?" got zero hits. So did "What movies has Lily Tomlin starred in?" because that's unlikely to be asked in a FAQ."
