Thanks for the good feedback!
There are a couple of things this brings to mind:
1) True interactivity is defined differently in different areas of publishing. For example, embedding a video in an enhanced .pdf or other format can be considered 'interactivity' because the reader/user pushes play and watches. But if you are teaching with Mathematica you understand the difference. Most enhancements in the last year or so in e-publishing have created 'dynamic' documents (links, embedded video, etc) but it is not really interactive.
Truly interactive publishing means you are interacting/engaging with the content in a meaningful way. Mathematica and WolframIAlpha create many ways to do this. Students actually observe behavior changes when they move a slider or enter a value that is immediately calculated. Embedded WIA widgets on a website allow users to input their own data and make calls to our curated data for immediate use/calculation. This creates valuable interaction that is as individual as the student using it.
2) If you are working on publishing your work from Mathematica, we have a growing interest from publishers to work with this type of content, and I would be very interested in hearing more details from anyone in this position. Specifically we have been talking with some of the leading journal and textbook publishers and have been also working internally on some future capabilities in this area. Actual applications and examples would help us to make sure our direction is correct, so please contact me, or send an email to email@example.com
and mention the Faculty Program.
3) We are advancing citation and bibliographic capabilities, so it should be something in our future development.
Keep the ideas and use cases coming. I always appreciate the unique insight and foresight of Mathematica users and how they utilize our technology.
