As is discussed regularly in the heap, there seems to be a steady decline in the overall quality of questions on StackOverflow.
I am nervous that this symptom will bleed into our site, and to prevent StackOverflow folks from thinking, "oh, I see, all database-related questions belong on dba.SE," I'd like to make a two-part proposal:
We be very careful about the quality of questions that we intentionally bring over to our site from SO. (I think we're already doing a good job of this, but repetition can't hurt.)
When we do VtC a question to migrate to our site, at least one of us adds a comment with some kind of indication that it is being migrated because it is a good and/or complex database-related question, not just because it is database-related (which is what they might think if the question just gets moved with a simplistic "better fit" comment or no comment at all).
This question identifies the need to clarify which questions belong and which don't. As per 1. I think we are already doing a good job of this. I just think we need to make our clarification clearer to those that aren't as familiar with our site...
