tl;dr: Allowing beginner-level "help me diagnose this" questions will generate large volumes of duplicates if the site ever scales. We need to think about how to structure things if we want them.
I have certain reservation about this.
I've said before that I don't think question-and-answer is a good format for the kinds of questions that beginners ask when they're just starting out. My reasons are twofold: firstly the format is less than ideal for providing the best help, but more pressingly the questions that result are of limited value and tend to generate many, many duplicates.
I'd like to address this by starting with an observation and getting back to my points in a bit.
Of course beginners have a lot of questions, and more than that if we compared notes we find that we shared many misunderstandings and failures to appreciate the implication of what we'd been told. Certainly we didn't all have the same set, but I'm sure that every pairing of two experienced programmers would generate a set of common "you wouldn't believe the stuff I didn't get at first" stories. These things are ubiquitous.
So it might seem that the world would be well served by a bank of these questions carefully answered to serve as a resource for the up-and-coming generation of beginners, right?
But the core problems are searchability and askers recognizing that existing question match their own. If you've ever mentored beginners you know that generally when a newbie comes to you with a perplexing issue the first thing you have to do is decode the way they present the problem. Because beginner share a set of misconceptions but they don't share a common mindset, focus of attention, and vocabulary to discuss either what they have done or what they expect.
This has two implications:
That having a relationship between the learner and teacher makes the translation more reliable and lets the teacher steer the students ways of talking about their programs and problems into a consistent and conventional groove slowly than a Q&A framework where the asker may be dealing with a different set of answerers on each followup question.
There are dozens or hundreds of ways in which they ask the "same" questions and don't accept that existing questions answer their query. Those of you who participated in the early days of Some Otherplace will recall the endless duplicate wars which resulted. The issue of experienced users answering duplicates because it was easier than finding an earlier instance was never resolved (which proves that the searchability issue is non-trivial).
If we are going to have beginner-level "help me out with this code" questions (something I have the feeling that many people are in favor of), we need to think about what they will look like on the site in the event that it scales up. For instance, do we want a separate category for diagnose and fix this code questions similar to the separate category for code review questions?
