Why is Instagram so popular?
It's just another technological fad. It will fade just like my space, fb, twitter. There will always be a new fad to replace the last fad.
It allows people all around the world to share pictures with each other and follow friends, celebrities and people from all over :)
It helps girls touch up their pictures so they can try to trick us men...yeah their eyes aren't that blue
Cuz it's awesome.
