Better needs a scale to be measured against. And that scale will vary among the different members.
I've made Cheftalk a home page in my browser because of the high signal to noise ratio as well, and a phrase I've applied to cheftalk before. As a counterexample, I consider www.discusscooking.com to have a low signal to noise ratio, but it's a busier site than this one so there are lots of people obviously pleased with it.
But there are many good web sites for cooking and I don't think any of us here only visit Cheftalk to the exclusion of all others.
