This. I first saw a raw_nerve post here on HN, and that's how i got to know of Aaron. Such writing requires an ability for introspection, among many other things. I find it hard to contemplate how someone with such a mind could possibly commit suicide. Sad day, indeed :(.
Definitely. He wrote a bunch of blogposts last year on improving life, called "Raw Nerve": http://www.aaronsw.com/weblog/rawnerve
Wonderful writing.
