It's a very nice reader. I recommend putting all of your CSS in one external stylesheet and combine your JavaScript into one external script file. While I'm at that your HTTP expiration date for your CSS is tomorrow, even though you have cache busting. Set it to for the longest possible time and just update your cache busting version number when you update the CSS. The benefits are caching. This will be very important for an embedded product. I also recommend not using JavaScript to detect IE versions to load external CSS and JavaScript, especially since you're already using the better means, conditional comments.
Wow, we're really flattered by these posts on HN (Crocodoc co-founder here).<p>The HN community has been really supportive of us as we've been working on this. Lim Cheng Soon from Hacker Monthly was even kind enough to give us permission to use some of their PDFs to showcase our viewer.<p>This PDF (HM issue #1) is one of my favorites: <a href="http://crocodoc.com/pUY6tB" rel="nofollow">http://crocodoc.com/pUY6tB</a>
