is one way to get in touch with your own old friends and family members who do not live with you on board, moreover its a very useful place to socialize with people (new ones), and get to know them, we do share ideas and opinions, we sometimes argue on some subjects,we make fun of each others, we talk crap, we talk serious, and seeing new nations and their tradition without experiencing them physically is also an advantage, for all the above I can say that social media is so not useful for people who won't admire them and use them in the right way.
