Compared to face-to-face, Internet communication is two dimensional....As distractions multiply, fewer receive our full attention, and nuances are neglected. We don't look at the man selling us coffee, never mind shoot the breeze; we're too busy fiddling with our iPod. I've witnessed wedding guests with more qualifications than they have chromosomes text-messaging during the vows.
Developments, yes, but progress? ...The nuances are no less valuable to us than they were to our forefathers, nor are the joys. Abandon them, and we miss out.
In some ways, I agree--that to miss out on intimate conversations with actual people is not a good thing and can lead to feelings of isolation and despair for some. But small talk is not for everyone and sometimes it can lead an introvert to feel uneasy, bored or just alienated. However, Blyth says it's important to overcome shyness and gives tips such "the more engaged we are, the less nervous we feel" to those of us with little aptitude for small talk.
Overall, the book is quite good at teaching how to engage in good conversation--from a romantic talk with a partner (in a chapter on pillow talk) to how to wage a word war with those who insult you. It's a good read.
