Jonathan Corbet is great, as the first example I thought of. I don't want to try to make a proper list right now, it feels like it would get nitpicky and waste an hour to do so, but I could point to a lot of sites and blogs that do good tech and security writeups. Many without a day job of "journalist", but in this context they'd still be filling the role as press.
Jim Salter, though he no longer works in journalism afaik.
