I subscribed to MacPowerUsers 11 month ago.
Thanks to Kathie, David and their guests I dicovered many great productivity apps and workflows for Mac, iOS along with the tech gear in between.
Since then I have been using a lot of them like TextExpander, Alfred, Moom, Default Folder X, Hazel, Keyboard Maestro to name a few.
David's screencasts have also been very helpful. I watched them when I decided to switch to Omnifocus as my main task management app, use Hazel as a key file automation tool, and go Paperless. I quickly got both a panorama of what is possible and numerous very handy tips and tricks immediately applicable.
My favorite eposides so far are: 3, 51, 81, 84, 134, 114, 145, 167, 192, 206, 217, 221, 238, 307, 315, 322, 386, 390, 392.
Congrats to Kathie and David who have been creating informative episodes for eight years.
In my opinion MPU is definitely a must if you are using a Mac/iPhone/iPad/apple gear or want to constantly sharpen your tools and expand your horizon because it is jam-packed with tips, apps and great workflows.
