I still remember him being one of the best writers about tech (a bit more than "journalism" in that a lot of it was of more evergreen value...) from the dotcom boom and then the peak "interesting" web apps period (2004-~2015 or so, when AJAX/etc was still new, and things hadn't calcified so much). Didn't know about his later health issues, I assumed he had just moved on to other interests naturally. RIP.
