Amazon adds Instant Previews for Kindle shares

Amazon has expanded Kindle users’ ability to converse about their favorite literature, announcing what it calls Instant Previews. With Instant Previews, a Kindle user can share recommendations and quotes from Kindle books to individual friends, and those on the receiving end will then be given “instant” access to a free preview of that book. It'll come in handy for book lovers who often share recommendations among themselves, but ultimately serves to benefits Amazon as it ropes in new customers.
