Michael Keithley has been focusing on productivity since when paper planners were the only options. He became an early adopter of digital tools, and still has a technology graveyard of PDAs and other electronic productivity tools.

He emphasizes that it's important for a digital system to allow for sending an email to the list manager. You can watch the entire conversation from October 2025 at GTD Connect .
