Koenig used to have a tumblr, which is where he first published his sorrows, very intriguing. I follow him, but he has long gone silent.
I've never read Obscure sorrows but the name seemed oddly familiar... There should be a word for feeling of _I know i have seen/heard of this somewhere_ and trying to figure out where from. Anyway it was recently discussed on hn - https://news.ycombinator.com/item?id=48611411
These two feel especially relevant:
Small Is Beautiful: Economics as if People Mattered - E.F. Schumacher
Tools for Conviviality - Ivan Illich
and
The Dictionary of Obscure Sorrows - John Koenig
