Relationships does not replaced by technology.

As not only the social world evolves, but also the business world evolves with Facebook and Twitter – how does your business survive with technology changing every moment? Well, technology may be changing, but social skills remain the same. You have to know how to communicate with every customer you have. The business that survives in this world is one that knows how to Twitter relevantly and also knows how to shake a hand and make a proper introduction. You may be on Facebook all day long, but unless you are developing sustainable relationships by meeting in person, your Facebook skills are futile. You may prefer e-mail, but if an important situation arises and you do not have the professionalism to pick up the phone, it will appear you did not appropriately handle the situation. In business, e-mail is both an opportunity and an easy way out. Even though you can be very eloquent over e-mail and it is an opportunity to really think about what you want to portray, too many times it is used impersonally. Even though some businesses prefer to communicate via e-mail, it can also become inconvenient. Say you want to schedule a lunch, but instead of calling, you e-mail. Chances are 10 different e-mails go back and forth about what date, what time, when, where, when in reality one phone call could have accomplished this scheduling.
