This summer I went to a summer camp that I loved, a summer camp for creative writing. It was amazing being surrounded by people who shared the same intrests and knew how it is like to write and share work. During that week we did quite a bit of peer editing and it was exhileratingly terrifying. To put out your work and let people criticize it is nerve-wracking. But it's also relieving, knowing it now isn't all in your head.
Another experience that shaped the idea is rereading past work. You hate some parts and love others. Usually the ones you dislike is the ones when you were writing loved. It's a bit funny in reality. I love rereading because I can go back and fix what I dislike. Then read out loud for grammatical errors (which I'm prone to making).
That's where this idea came from. That rush, gave me this idea. I get really scared by sharing with people I know. On the internet the blow of critism is paddened and is easier to accept. There is an edit function for the creator so they can fix their mistakes.
