Why don't you market this product towards aspiring technical writers? That seems a whole lot more logical to me.
You know what, we have put a lot of thought into this product and how to market it, but we have never considered that. It is definitely an interesting idea, and I will think about it! 
I could insert a paragraph into the sales page saying that it's useful for professional whitepaper writers too - but would that make a half-baked impression?
