Since its beginning, juliovision/dbr has existed in parallel to the board. It's part of our culture. The discussions here have been more numerous and more detailed than anything posted on the main page. And we frequently anticipate the main page. Personally, I like that. We're the cool kids.
There is an understandable argument for attaching comments to the main site articles. However, I haven't seen any other site that presents a compelling argument for changing our (more advanced) model. We have a fabulous community here. I don't want to dilute or fragment it. It works.
Do other models work? I'm sure - it's a wide, wide world. But we've found a sweet spot, and we want to maintain it.
