@JohnPhilpin Thanks. Most of what I've seen in the Twittersphere and some of the note taking and tools for though space is incredibly thin, so I've been trying to dig into the background and history for some more considered approaches by studying people who've spent years using similar systems rather than people who've (re-)discovered them in the last year or two and are reinventing the wheel. Better to look at Mortimer J. Adler's writing and examples. Manfred Keuhn is a more recent writer with both experience and some appreciation for the history of the space.

For others on mb, it might be worth reading (and listening) to @AndySylvester.

@jeroensangers idea is similar to some of my process as well. @JohnPhilpin I use the random note occasionally to review over old tidbits, but I'd recommend against using random note for progressive improvement. You'll probably find that you're more productive and have more fun by reading and impoving the notes on the areas you care about and enjoy the most. Not coincidentally those are also the places you're more likely to re-visit and re-poen as well.
