Empty Email In-Box, from a Webcomic?

So I've been reading this hilarious web comic called PvP for the last couple of years mostly for the Dungeons and Dragons references initially. I've kept reading though because I kind of like the characters and the author blogs about the process of writing the strip and other things besides.

Today he posted a great link to tricks to using email better. These aren't limited to a single platform, just good best practices. The idea is that we can in fact have an empty email in box, in fact it's a really good idea.

Useful practical advice - from a comic strip based on D&D and online gaming. Who would have thought.
