I've been futilely reading his recent FriendFeed and Twitter updates for some inkling as to what could have triggered this tragic act.

Not so much as a smidgen of a hint. His comments seemed consistent up until the last with no hint of despair. No wonder this caught people by surprise. It's flabbergasting.

My condolences to everyone close to Dan. Although I didn't know him personally, he seemed like a terrific guy.

What sad news.
