But it's kind of a weird and poorly constructed argument:
It’s easy to see why some readers would feel whiplashed by the current, critical coverage of Facebook and Google, which seems to come out of nowhere.
Whiplash ... came out of nowhere ... so journalists changed their view too fast then. Next sentence:
That’s our fault as journalists: We’ve been too slow to spot how things have changed
Wait, did journalists change their views on tech too fast or too slow? It seems to be both at once in this paragraph.
Later he appears to lament the historical dearth of "serious tech journalists", but he defines serious as journalists that "hold tech to account" which in turn simply seems to mean attacking them because they're big. I guess I'd use a definition more like "understands technology", with Jon Stokes at Ars Technica being a good example.
We do need a new model for tech journalism and indeed all journalism - we need journalists who are more interested in neutrally reporting accurate facts and news rather than engaging in poorly thought out social advocacy. Given the contents of this essay I'm not holding my breath.
