Instagram is a life saver. This is the only only social media which I access. I am following many informative pages which is very useful to know what is going on around me. I can chat with my friends. I post my pictures on my profile nd share my moments with my followers. Also one can use the story feature there, in this the pic posted will remain there for 24 hours only and then it get deleted automatically. Support & service of instagram is very good, whenevr you feel to change your privacy settings you can. Instagram is the best timepass, I can just scroll down the pages which I follow, whole day without getting bore.
