The problems Software Quality Assurance has shouldn't have any effect on our site: Joel Spolsky warned about the issues of trying to segment the programmer population into progressively smaller camps, and the fact that they can't field enough questions, to me, indicates Spolsky wasn't far off the mark in his original assessment. Many, although perhaps not all, questions related to the topic are on-topic here and shouldn't be migrated to a struggling beta site.
As to the other questions: as Anna points to, they're not on-topic on Stack Overflow, and are on-topic here. Stack Overflow is for very specific, here-is-my-code-and-I'm-not-sure-where-I-went-wrong-with-it questions; Programmers.SE is for conceptual I'm-planning-on-doing-this-but-need-help-with-the-big-picture questions. The topics you list as being better off on Stack Overflow are are our best, most useful questions: the questions that most resemble what Programmers.SE is about.
That is, if these questions aren't on-topic here, what is? The junky questionsjunky questions that aren't good enough for Stack Overflow? We figured out early on in beta that wasn't going to work, and that's why Programmers.SE was launched as the conceptual yang to Stack Overflow's concrete yin.
