Seems interesting, but I really think you should start with a landing page that gives folks an idea of what the product is, and a couple sample use cases. Then a big button to "Start Using Bookvoid", and then drop them into your sample. As has also been suggested, easy to see/use links to incorporate Evernote and other sharing platforms would also be a good idea. FWIW...
