I agree with the curiosity around these questions - it's definitely hard to see the long-term benefit here. However, long-term benefit is something that often needs to be proved (to exist or not exist) vs. something that can necessarily be predicted without substantial prior evidence, which we don't really have since the site is still very new. It's true that we can draw parallels between questions we see here and similar questions we've seen on other network sites, but that's not necessarily a correct (or useful) correlation to make on new sites.
To provide a contrarian view, many of these questions could be rewritten and possibly turned into public wiki articles on skills that are important to various fields. Of course, that idea presents its own challenges (do we want to be the warehouse for qualifications listings for a ton of job descriptions)?
However, as others have pointed out, where else in the network are these kinds of questions going to be on-topic, and how much of the motivation to begin this site has to do with career transitions, advice on getting /changing/starting/leaving jobs, and other somewhat advice-based questions. I'm starting to see the wisdom in at least attempting to answer these questions without jumping on the "too localized/non-constructive" train just yet.
So long as a question is phrased in such a way that it's answerable, I'm starting to think that these sorts of questions (at least at this very early stage in the site) or more helpful than hurtful. If anything, the first real problem I think we'll start to see with these questions is the need to close many future questions as duplicates, but only time will tell.
