I always prefer instagram over facebook.there is less drama in instagram and we have our privacy on it .instagram is a place where you can put your pictures and videos to your prefered audience .i realy like the option of making your account private .which will help you to have your known friend circle .
There is no any option of putting status etc on instagram .which is helpful to see less drama of people.
Its really a place to promote yourself putting your pictures to audience and also its a album of your life .like life thorugh pictures.it also help to edit our pictures there is options of editing in it .we can see your friends and celebreties pictures through instagram .really good experience
