Today I was reading a real live book at a café. Normally I only read books available on the kindle but I was reading the "Evolution of God" by Robert Wright (because the book itself does not come out officially until next week). Great book.
But the point is that two random people came up to me in the café and asked me about the book and we had a conversation about religion, good books, and more. Now I frequently get people asking me about the kindle ... but that is a more common technology conversation. Here we had a real conversation about real ideas.
I did that the other day when I saw someone reading Atlas Shrugged on an airplane. But as we all move to reading books on our devices, we wont know what people in our proximity are reading anymore and conversations between strangers will go down. (maybe this is happening anyway as you're much less likely to talk to someone with headphones in their ear).
