History has been a witness to this. What was the Cold War of if not almost 50 years of communication problem between the US of A and the Soviet Union? And aren't the telecom, internet, postal and so many other industries hinged on the need of effective communication?
However, we all have our range of communication problems. Some of us just don't know how to interact with strangers. Others, are better off communicating with just them. Perhaps that's why so many people create blogs to talk about themselves(?) Still others indulge in incomplete communication - speak half truths, share their feelinsg without telling the facts or vice versa.
