Per statistical results, the time used for Social Network Service (SNS) has doubled in the last 10 years in the US, and on the other hand, time for phone calls/meeting with people has decreased by 10%.
While I personally use Facebook and Instagram to catch up with the trend, and use e-mail and texts for work, I always try to secure time to visit sites or meet with counterparts in person to maintain close relationship.
What I have found recently from work is that people who try to do business only online tend to be afraid of facing their counterparts. Being unable to leverage both online and offline effectively means that the interpersonal communication capability is not sufficient. We should pay attention to it to drive things better, especially when we live in an SNS era.
