It’s there to ensure that people don’t over work themselves in fear of not being able to compete with other’s ideas.

If you’ve got an idea, but it’s complex to explain, try writing a draft and then keep revising it until you can express it more clearly. Sometimes you just have to write something, no matter how bad, just to get a better sense of the way to explain it clearly. You could also try posting something, and then readers can ask questions and help you refine your explanation. You can then always re-draft and post it again in an improved form.

A note to all contestants, you don’t have to get it perfectly right the first time. Delete and repost as many times as is necessary to hone the text.
