About nine months ago, I became caught up in the TiddlyWiki concept, and spent a month or so exploring the different implementations. I was particularly impressed with the MonkeyGTD. There has been a lot of good work done on this approach, and the idea is fascinating. However, and it might just be because I am somewhat old-school, I found it problematic that the TiddlyWiki approach bundled the application and the user data together on the same page. My concern is that with my data getting so intertwined with the data management and presentation engines (both of which are updated and modified very frequently), there is a big potential for data loss. I know that there are backup methods, and as a user, I never attained much competency in tiddlywiki, but nevertheless I did repeatedly loose data (in part because I did not sufficiently grok the UI, no doubt), and abandoned (temporarily anyways) the method.
I'll certainly be watching the development of this idea closely. I think it is somewhat parallel to the notion of launching notes in a browser for FCKEditing (to be saved back to the pb note). I seems obvious that there are some exciting possibilities for extending the capabilities of html-based pb notes.
Be vewy quiet. I'm hunting wabbit.
