Great feedback. We are too light on details. I'm adding a more detailed description shortly.

The original idea with the video was to show the types of functionality that FormBig exposes (eg: integrated logins, JS-based logic, rich text editing, etc) rather than the details of how one achieves them. However, I think since we went that path it is important to get more details in the body of the page.

Thanks for the pointer to MS Lightswitch I'm learning more about it now.
