Why do so many people like instagram?

[Literally]

I waited a very long time to finally get an android phone, and finally download instagram.. and its the biggest piece of **** ever... there is no customization on photos, I've known better editing/sharing websites than this.. all my pictures look like shit
why is it so hyped up?

I don't? Guess it's all hyped up because of the idiotic celebrities trying to make the "next big thing" thats really just as interesting as a steaming turd.

Instagram is a free photo sharing program launched in October 2010 that allows users to take a photo, apply a digital filter to it, and then share it on a variety of social networking services, including Instagram's own.
A distinctive feature confines photos to a square shape, similar to Kodak Instamatic and Polaroid images, in contrast to the 4:3 aspect ratio typically used by mobile device cameras.
Instagram was initially supported on iPhone, iPad, and iPod Touch; in April 2012, the company added support for Android camera phones running 2.2 (Froyo) or higher.
It is distributed via the iTunes App Store and Google Play.
