It's great to see on-line initiatives in published form! It's also extraordinary to read a book about social media and current state of communication written by the actual users, bloggers, specialists. When I read the first edition of Age of Conversation I felt that I am experiencing fresh breeze of opinions, tips and views. The type of 'hellou! look everyone! this is us and this is how it works!'. The antithesis of academic study about communication - tones of which I had to go through at the university.
I really enjoyed it!
More about the project here and here, the list of participants of the second edition (available to order from this site) here.
Worth buying, your money will go to this charity!
