Social Networks and their issues

Today, we have a lot of Social Networks available to be which make us unsocial people. We have Facebook, Twitter, Instagram and others. I don't have nothing anything against that, but people are very unsocial while they are "posting" to obtain "likes" and "shares".

If you want to certify that this, go to public places like restaurants. You will see that people who are accompanied don't interacts with each other anymore. They will be very busy accessing their Social Networks profiles.

That This bothers me a lot because I think that the real social networking we is make made by interacting with other people in real life.

Why that is this behavior is happening? I don't know. Maybe this is just me getting old.
