Exactly! Also, I think his disappearance was a strong statement, too (we just don't know what it is). He appeared to be whimsical, but if you read his writings (since I don't know any Ruby this is all I can do) you quickly see that he is anything but. It is obvious that a lot of thought and planning has gone into those "whimsical" essays.
AFAIK, he didn't have a blog proper. But his writing can be found here: http://viewsourcecode.org/why/. I reread The Poignant Guide every now and then.
