I scheduled (with org-mode of course) going through and reviewing each section spread out over a week or two... certainly didn't adopt everything but learned plenty and ended up with a nicely configured org-mode setup with conventions I've been evolving ever since.
On a side note, the compact guide is a good read if you are somewhat familiar with org-mode - they even provide links to some advanced workflows of some users.
