One of the best lessons I've learned is, that 'bookmarking' or 'save for later' for me are just fancy words for 'procrastination' and if I want to learn something, my best bet is to do it now, as I rarely re-visit my bookmarks.
Surely this could vary from person to person, their working patterns, planning, and organization skills, thus the discussion.
How often do you re-visit your reading/save for later list?
