I think it's a shame what TW has done with YNN. They did the same thing here in the Syracuse/Utica region few years ago, by moving all of the anchors to Albany. This was back when it was still called News 10 Now, and the Albany operation was Capital News 9.
I rarely watch YNN because I know 99% of the time it's pre-taped. Sorry to use a cliche slogan, but I prefer my local TV news to be "live, local and late breaking." When reporters are covering a developing story, I want to see it live, not a lame "on scene" look-live from two hours ago. Even if there's still nothing "new" to truly warrant being live, the "on scene" bug just translates to "OLD NEWS" in my book. Either be there live, or do something else like an anchor VO, VO/SOT, or a straight package without trying to pretend to be live.
TWC doesn't care about YNN's ratings, though. They just use it as a selling point to get people to subscribe to cable, or to prevent people from leaving cable. That's all it is. "We have all this great stuff, but if you don't have cable, you can't see any of it." And people actually buy that.
At least as a trade-off for losing its news anchors, the Syracuse YNN studio gets to provide weather for everyone. And the YNN parking lot in Syracuse has the distinction of being home to the YNN "Stormtracker" vehicle, which I'm pretty sure has never actually been used to chase an actual storm, let alone broadcast anything from said non-existent chases. It's nothing more than a Hummer with YNN logos and the word "Stormtracker" plastered on the sides.
