This is for a widget that will be hosted on third party websites.  The
widget will allow users of those sites to interact with our content.
The widget will be written in JavaScript and HTML.  The widget will
retrieve content and submit user interactions using Ajax and JSONP
(supposedly via a REST API :).  Users will not be required to log in
to interact with the content in the widget.

Thank you for your feedback.  Some of this is new territory for me, so
being steered away from doing things the wrong way is very helpful.
