I was shocked and saddened to learn of the death of Mark Fisher. Mark was one of the pioneers of theory blogging and para-academic independent publishing. I learned a great deal from his blogging at K-punk, where he wrote incisive political commentary and undertook bold philosophical speculation, and he blazed a trail when he published Capitalist Realism, which brought the Zero Books series (now succeeded by Repeater Books) to international prominence. He supported a lot of us in this corner of the blogosphere, and I personally owe him a debt of gratitude as his recommendation helped make the publication of Awkwardness and its sequels possible.
Mark was truly a model of how to pursue a life of public intellectual engagement for a generation of young thinkers.
An und für sich 
A real loss. Met him in London a couple of years ago, he’s a force.
