Hey, I need advice on my website.
It is a platform on which you can either begin a new story or continue an existing one.
Every time you write to a story, you have only 5 minutes.

So the idea is about collaboratively writing stories.

You can visit the website on nessir.com, a few 4chan users already tried it, some liked, other never used it after register.
Here is the longest story ever written yet: http://nessir.com/viewer.php?textid=3

I want to know how should I develop the idea further, and would you use it, why not? And if you think it's a fail from the beginning, just tell me so I don't lose any more of my time and effort on it.
