I think the author tries hard to ignore the role of technology. 1. It's clear that most books will be ebooks , especially for people interested in book communities. 2. It's pretty easy for anybody with an interest to form an offline(or offline/online) community anywhere using digital tools. reddit meetups are a good example.grubwithus is another. And they facilitate better communities at a cheaper(sometimes free) price. 3. The capability and benefits of online communities is always improving. Google+ hangouts is the latest example. Maybe in the future they'll replace offline book communities at all ?
