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.

Brian Krebs comes to mind.

Jim Salter, though he no longer works in journalism afaik.
