People keeps asking, so here they are. Books to read if you want to update yourself on new media:
I’ve read all three and can really recommend them. Then, Lasse Klein and a couple of my readers have recommended this one: “Linked: How Everything Is Connected to Everything Else and What It Means”
…so I guess that will be in my next shipment from Amazon…
Update:
From the comments: Espen points me to “The Wealth of Networks: How Social Production Transforms Markets and Freedom“. Interesting content and interesting project. A creative commons licensed book available in many different versions.

You seem to have forgotten the book that encompasses them all: Yochai Benkler’s The Wealth of Networks, available as a book, an online book, and as a wiki for readers. See http://www.benkler.org/wealth_of_networks/index.php/Main_Page
Highly recommended.
Thank you. That one seems really interesting. I have updated the post.
