Thanks, Karyn. No doubt this is a bit simplistic, but my aim was to show how PKM could work for people not used to it, especially those feeling overwhelmed with information online. I should have added exercise to the top of the diagram as well, because it's while I'm cycling or skiing that I get my best ideas and threads seem to gel.

The essential component, IMHO, is the act of writing it out and letting others see it.
