We did some of our own research into the most frequently asked questions on the Guardian site and what you find in this book is our attempts to answer some of the most interesting, taxing and bizarre. Everything from 'What is quantative easing?' to 'What does human flesh taste like?'. And here it is – eclectic, discursive, and not always right. That, in the digital age, seems a motto to be proud of. We don’t have all the answers, but we will never stop asking questions, and we hope you don’t either.
