Having downloaded a couple of social media platforms like Instagram, Twitter, WhatsApp and once upon a time Facebook, I use or maybe am addicted to WhatsApp. 

The reason is pretty usual and not something out of the box-to stay connected with closed ones. 

Being far from family and friends is hard, especially when you live on a different continent! I use WhatsApp for staying in touch with my loved ones daily. I am the kind of person who keeps asking about my loved ones health and life. So, the only source for me is WhatsApp as it is easy to use, and most importantly everyone else has it too. They don't have to download a special app to stay in touch with me and vice versa!  

I can recall, in early 2000, when there was just Facebook, communication with the people outside the country was difficult. Although Facebook offered the chat option, that wasn't feasible all the time. Moreover, there were no voice and video calls back then! Sharing personal pictures and videos on chat wasn't an option back then.

With the advancement in technology, life has become easier for long-distance relationships. Although it has its cons, we as sensible adults can work on it.
