This is quite heavy reading. After all, it is a researcher who has written it, and it shows (for instance, about one seventh of the book is notes). It took a while to get into, and even then it happened that I lost track when there were too much psychological references (I did better with the philosophical ones and, of course, with all the computer science stuff). So, what is this book about? It focuses on the human side of Human-Computer Interaction and Computer Mediated Communication (by email, IRC, web-chats, MUDs and such). It addresses important and interesting questions like how ones own personality is affected if one on the net puts on another personality, or even another gender, and how ordinary people reacts to the question of artificial life - whether it is actually possible or not. Turkle shows that exploring and developing ones personality at the Internet can be both good and bad. Some people eases personal pains and overcome difficulties by experimenting with what they want to become, while others grew envious of the digital alter egos and are left feeling stuck in their real lifes. Very thought-provoking stuff! What I liked best, though, is that Turkle takes MUD and IRC dead seriously.
