I didn’t know Bill Zeller personally, but Lifehacker covered at least two of his projects—Graph Your Inbox and myTunes. This week he hung himself and published his suicide letter on his web site to explain why. The letter is an intensely personal missive that gives a brutal look into what it’s really like to live with a history of child abuse. Pre-web, that letter would’ve been written on paper and read only by Bill’s closest friends and family. But this week, to make sure his death and experience was not in vain, I found myself calling and writing friends and family who have suffered that kind of abuse to tell them how much I care about them, and how grateful I am that they survived. (Here is the suicide letter, but before you click, be warned that it’s heavy reading which could turn a workday on its head.) Thank you, Bill. Rest in peace.
