Instagram

Instagram is all about pictures. I never heard of it, until my facebook friends have posted on my news fees stating that my friend posted a "picture" from instagram. I started using it and now I am addicted to it. I like looking at my friends pictures and celebrity. Im not the only one whos addicted, i have seen people post pictures like 4-5 times a day. My opinion on on girls using them to get attention when they are posting themselves almost half naked or being so sexy and boys use them to look at girls. I want to know what is your opinion on instagram if you have one. How did instagram boom so quickly?
