Steve,
"My thinking is that Tiddlywiki comes as close to Nelson's vision of hypertext as any other application I've used" - sounds like the start of a paper (didn't you post something about a hypertext conference a short while ago)
I wrote a paper for a conference in which I sketched out a design for a tool for place management (using TiddlyWiki of course). I struggled with justifying the choice of TiddlyWiki, I ended up going up a level of abstraction, saying that hypertext is the most obvious way of dealing with communicating complexity. I don't think I quite managed to make an argument that TW is more suitable for hypertext writing than other hypertext authoring tools.
In the forthcoming year, I hope to build and trail the tool in a live project, I was wondering if i could turn it into a case study for a hypertext conference as well as a place management conference.
Something about making the case that hypertext literacy skills are a key to understanding and communicating complex ideas, and that personal hypertext authorship is the first step.
I wonder if we could have some kind of discussion about this, maybe on the next hangout?
best wishes
Alex
