I recently started making read/review-related GTD projects to be more disciplined about consuming websites and books. I do this because I want to extract information from them and not just read and forget it.
The current one is 43folders.com, which is old, but still contains many valuable tips and tricks regarding Mac productivity. I’m unsure if there is anything like that today like the Mac blogging scene was from 2003-2008 – maybe MPU Talk — when everybody was obsessed with GTD, QuickSilver, Mac OS X, and productivity. Good times!
