Thanks Eric, Very good. Very very good in fact. So good it should be in the manual.
I liked Måns' term 'semi-Socratic dialogues' - from 'the one where Eric advised Måns to read the manual' . Perhaps 'a personal non-linear semi-Socratic dialogue notepad' would be the innovation education is looking for. The students links from the dialogues with his Master and to create his / her own open source leaning document. It would be a good partner to TiddlyHub.
