My video on conversational versus issue structure

I've just created my first video production (using Camtasia) and I've put a version of it here in the Video collection. It's meant to be a short infomercial on the benefits of issue based structure. I'd like to produce a similar video comparing the structure of a text document, like an article on an issue (e.g. regulatory vs technology approaches to global warming), with the structure of the corresponding issue map.

I'm curious if anyone in this group sees deeper issues about issue based deliberation that the video might raise.
