We’ve been hearing a lot lately about the struggle to keep your email inbox under control. Our Cool Friend Mark Hurst outlines a scheme in his book, Bit Literacy. Lifehack.org tries to help you avoid email bankruptcy. Today, Biz Stone pointed to an appealing strategy: three.sentenc.es. You choose a number—two through five—that will be your personal sentence limit when responding to any email. Committing to curbing verbosity might just make the task of responding to all those emails less overwhelming. Have any other inbox-wrestling tips to share with us? Or are you more of a Cool Friend Dave Freedman Perfect Mess fan?
