Intro for use-cases document

I was tasked with writing an intro for the use case document.  I believe
Ivan said he would help ensure it got into GitHub correctly, but I figured
sending to the entire group wouldn't be a bad thing.

<h1>Introduction</h1>
<p>Every 100 years, a piece of literature is written that is so grand, it
becomes canon and will be read and studied for countless generations.  This
document is not that piece of literature, but the following use cases
outline the functionality desired by publishers, authors, and readers to
ensure that the next great piece of literature can thrive on the open
web.</p>

<p>The printed book has had hundreds of years of refinement, typesetting,
and features added to make it an amazing form for conveying both fiction
and non-fiction content.  These use-cases outline the requirements of
publishers, readers, and authors for being able to consume content on the
web that is at least as accessible (or hopefully more accessible) than in
print.</p>



Am I missing anything?
