A question about a question

I'm turning to HN for some advice, but before I do I have a question.. to make the most of the actual question I want to ask :)

I'm looking for a mentor/advisor and I am preparing some material about my startup. I'm detailing everything I have with a video demo, 2 page PDF with an overview and my CV.

My plan was to lay it all bare at HN and ask for advice about the content. But before I do I want to know if that sounds like a really stupid idea, basically telling everyone everything about my startup?

Are there pitfalls to my approach?
