I still stop by almost daily, but unfortunately it’s dead here. Most of us largely “TV” people are dinosaurs and everyone that can hold a camera now, thinks they’re a “filmmaker” and frequent the sites that cater largely to that end of the spectrum. But even those message boards are not what they once were, and even with their huge member base and visitor numbers, sometimes it can be the better part of a day or more with no new posts.
I had heard several years ago that a lot of this type of activity was moving to Facebook groups, but from what I’ve gathered on some of the other forums, a lot of those FB groups are very jingoistic and full of fanboys of particular manufacturers(especially cameras) and any perceived slight against the equipment results in people being kicked-out/banned from those respective groups. They seem to kind of a parallel/mirror society today: continued and increasing division, tribalism and extremism.
