My goal is: "I want to produce novel, powerful ideas." A computer-supported thinking system is helpful insofar as it supports that. But it's hard to evaluate those systems empirically because such ideas are rare. People who blog about note-taking systems don't produce them.
Seymour Papert used to say "You can't think about thinking without thinking about thinking about something". In other words, it will really help to have important issues and ideas, and things to learn about that require much better thinking. Then, the many things that are known about thinking, how poorly we are generally at it, and what we've learned about doing it better, can be brought to bear.
