I don't read any gaming site on a regular basis in the sense that I go visit their front page and click on a bunch of articles. But generally speaking, if a Kotaku article gets linked here, I go read it unless it's about a game I'm not at all interested in. Sure, there's the clickbait-y stuff (which is unfortunately part and parcel of running a lot of online news sites these days), but Kotaku's got a bunch of people doing good investigative work like Cecilia D'Anastasio and Jason Schreier, and I enjoy a bunch of their writers. I'll read most anything Gita Jackson writes because I love how sometimes she takes on the weirdest beats, like "Sims sex mods writer."
So yeah. Kotaku writes good stuff. Just like Waypoint, Polygon, etc. write good stuff.
