I am not convinced as Andy suggests that reading retention and note-taking are fundamental skills of knowledge work. What's more I have a suspicion that many knowledge workers over-rely on the act of collecting notes. Too much note taking is pernicious: it feels like doing something, while also giving you an excuse to endlessly delay putting forth your own thoughts until you have all the pieces. Rather than collecting and storing thoughts, the deliberate practice of knowledge, the expression of creativity that comes from play, necessitates sharing nascent and feeble ideas.
