Sweet. Scribd has an HTML5 document viewer so a PDF viewer is certainly doable. Maybe this will be included someday as a minimal PDF viewer in firefox.

Now all we need is a proper javascript printing api and almost all business application can be done in the browser.

But this is pure client-side. Scribd does server-side generation of the HTML5 page.

Yeah. If this gets more robust and productized, it just might eat Scribd's lunch.

...not sure. They're not exactly charging for Adobe Reader. If end users or site owners switch to a less bloated viewer, they still keep using Adobe's PDF format.
