Commentary by Stephen Downes

Suppose you wanted an ebook reader that would work on any platform, including mobile platforms, that allowed you to annotate the work, and perhaps share with other people. What you'd want to do would be to build a server-side converter, then create an HTML5 interface that supports this functionality. And that's exactly what you get with Crocodoc. View PDFs, Office documents and images, display them in your browser without Flash or plugins, add comments, highlights, drawings, and other markups, share them and embed them anywhere. Note that "Crocodoc is not intended for directly editing documents like you would in Google Docs or Microsoft word. Rather, its collaboration tools allow users to add comments and markups in a layer on top of the document."

Here's one of my documents shared with Crocodoc (I've set the height to 200 just to keep the gap in the newsletter small; it defaults to a much more usable 600 pixels; just click on the Crocodoc logo to see the document on the website):

I've created a public directory where you can upload your own PDFs and try it out (please keep them on topic): here is the link to the PLE & Connectivism research folder; if you are logged in and view the document through this link you will see the markup options menu (top of the document)..
