I may be late in finding this, but I have been living it for about 3 years now. Inbox Zero is great for everyone, and programs like Apple Mail and GMail make it easy because you can Archive messages in a single folder and search them easily. It’s interesting to peek at another person’s Inbox (without looking at the content) to see if they are an Inbox Zero person or not.
I think half the fun of watching this video is tracking the GenX/GenY speak of Merlin Mann, who operates 43 Folders. “The default state of an e-mail should not be ‘keep sitting here until I start weeping’.”
