So I think I might have an idea to talk about: "Designing the Socialised Book".
What does a book designed for groups, rather than individuals, look like. After all, most books (artefact or instance thereof) see group usage: book groups use many copies of the same book. Friends and family share the same copy of a book. Books have a healthy secondhand market.
Given that physical books are (to use a coding analogy, sorry) all instances of an original, ur-product... what are the ways we could design them (physically, digitally, across both divides) to enhance their status as social objects? They're already wonderfully socialised; now how do we embrace them?
This cuts across some of Lucy's Social Reading ideas but also is somewhat different to them, so I don't want to get in the way of that - it's about new ideas for publishing and product, and takes a lot inspiration from some things I said to the games industry about what they can learn from other, already-socialised products.
