In September 2004, Mann founded and began the exclusive writing for the 43 Folders, a blog about "finding the time and attention to do your best creative work." The blog was last updated October 2011. Mann coined and popularized the concept of "Inbox Zero", writing a series of articles in 2006 on 43 Folders, originally suggesting for an "Inbox DMZ". Inbox Zero became associated with the Getting Things Done productivity strategy, and is a popular topic on lifehacker. In 2020 Mann stated he doesn't keep his inbox empty, and that the term has been misunderstood. Beginning in the mid-2000s, Mann wrote articles for Macworld, Make, and Popular Science. On August 18, 2009, Mann announced that he was writing a book, to be entitled Inbox Zero, about "how to reclaim your email, your attention, and your life." The book project has since been canceled. Mann also writes for his personal blog, Kung Fu Grippe.
Podcasting
As a companion to the 43 Folders blog, Mann launched the sporadically broadcast 43 Folders podcast in 2005. In 2007, Mann launched You Look Nice Today, a comedy podcast that bills itself as "A Journal of Emotional Hygiene," an effort he created with Adam Lisagor, and Scott Simpson. Mann has also produced QPR: Quotidian Public Radio, an audio podcast launched in January 2009, which was billed as "audio comfort food for annoyed liberals in fleece." Mann was one of the hosts on the MacBreak video podcast, and a core host on the MacBreak Weekly audio podcast. Since 2008, he has scaled back his appearances on the series. Beginning on January 18, 2011, Mann has co-hosted the weekly Back to Work podcast with Dan Benjamin on 5by5, where they discuss subjects like productivity, work life, and true costs of doing business. In September 2011, Mann launched Roderick on the Line, a weekly conversation with musician/writer John Roderick. In May 2015, Mann and technology blogger Jim Dalrymple started The Dalrymple Report podcast, more recently presented as "The Dalrymple Report with Merlin Mann," which continued through its 32nd episode on September 15, 2015. In June 2015, Mann began a 10 podcast series with John Siracusa in collaboration with Relay FM called Reconcilable Differences, which has since been extended. In October 2016, Mann began a podcast titled Do By Friday with Alex Cox and Max Temkin. The show continued after Temkin's June 2020 departure. Mann has also appeared as a guest on other podcasts, including the CBC radio show-podcast Spark, The Chronicle of Higher Education's ProfHacker,Scruffy Thinking,CMD+SPACE, and various episodes of Dan Benjamin's The Conversation.
Videos
In early 2009, Mann produced a short video series, Most Days. On February 26, 2007, Mann launched The Merlin Show, a video podcast primarily dedicated to long-form interviews. Mann has also published a long-running series of video shorts named That Phone Guy.
Other work
Mann has been described as the "inventor" of the Hipster PDA, a paper-based, DIYpersonal organizer that uses design cues found in David Allen's Getting Things Done. Mann is also known for his work with Quicksilver, a program used for quickly executing actions from the keyboard in Mac OS X. Mann was a member of the Tallahassee, Florida-based indie rock bandBacon Ray from 1994 to 1999. He started a cover song project of Will Oldham's song "I Am a Cinematographer."
Personal life
Mann started treatment for attention deficit disorder in 2008, something which he says helped his focus. He occasionally talks about his experiences with ADHD on his Back to Work podcast on the 5by5 network. Mann resides in San Francisco, California, with his wife and daughter.
