This is really interesting and very timely for me. One of my tasks that I’m working on for Proj240 is to put GTD into full effect, and this issue has kind of been a stumbling block for me:
One thing that annoys me is that Tiago doesn’t give any credit to David Allen or his book and system Getting Things Done, when this PARA system is in large part based on GTD - you could even see it as a summary or reformulation of GTD. A lot of the ideas in that essay are taken directly from GTD, even in almost the same language, to the point where I would consider large parts of that link to be plagiarism.
There are also parts that could also be seen as a refinement of GTD regarding projects vs areas of responsibility.
The marketing also strikes me as very sleazy, so I will not be giving this guy my email address or any money.
But in any case, reading this link and thinking about this distinction was incredibly helpful for me - this is exactly what was tripping me up in terms of implementing GTD.
