I spent about a month working with a tiddlywiki while I was looking for a good way to take notes and organize myself. Ended up ditching it for org-mode in spacemacs. I found the wiki format extremely clunky, and it lacks so many basic features that I want from an actual note-taking organization app, like scheduling a task and getting reminders.
If you are looking for a way to digitally implement GTD, imo, a personal wiki is a terrible way to do it.
I'm currently using this setup: http://doc.norang.ca/org-mode.html. That link is a literate programming doc that tangles into the org-mode config, cool stuff. This is the only sorta self-contained way of doing GTD that I have found personally. I think you could do it with a wiki and a few other tools pretty well, I tried mushing tiddlywiki and notational-velocity (deft in emacs I think) into my own GTD system, but couldn't really get it. Maybe I was doing it wrong though lol.
