It seems my ability to memorize has gone down drastically since high school (or probably elementary). I've messed around with freemind and orgmode and use them to track some things, but keep going back to marked up notes (I'll eventually convert to a cheatsheet if I use it enough) or books for programming. I'll highlight things that I don't remember. I personally don't have the gumption to memorize api's to all the different modules in Python that may or may not be PEP 8 compliant. I don't want to waste storage on how to set up ssh-keys when I do it once every X years. But I know exactly in my book where it is documented and highlighted when I need it. I can fall back to google if needed. As a visually learner, I know where in my physical books this stuff is located. Which is a drawback to ebooks as they re-flow there location of data on a page isn't consistent... I'm digressing now.
