We've had a couple questions since the dawn of Academia.SE asking for advice about undergraduate-related topics, the most recent being this well-formulated and generally pretty solid question. In the past, we've discouraged these kinds of questions. That was a while ago, though, and we've matured as a forum since then. Given how many upvotes the current question has received in such a short time, I'm curious what the community's current view is on undergraduate-related questions; should we continue to discourage them or should we allow them?
What I wonder about undergraduate admissions questions is whether anybody here can seriously address them, in a deeper or better informed way than just repeating information available from their college's admissions web site. I think very few faculty and almost no students could do this, at least in the sorts of systems I'm familiar with (private research university in the U.S.). For example, I have no idea how admissions officers evaluate applications from adults, or how the criteria vary between schools.
There are plenty of widespread ideas about how admissions decisions are made, which may or may not be true. Unless we either get answers from people involved in the process or get answers that point to authoritative information sources, there's a real likelihood of voting answers up based on how widely they are believed rather than how true they are.
I'd also be a little concerned if admissions officers started showing up to answer questions, since I imagine that would be incredibly popular and could easily take over the entire site.
So I'd be inclined not to expand the site's mission to include undergraduate admissions questions, even though this particular question is important and well formulated.
As for other sorts of undergraduate questions, I think there's less of an issue than with admissions questions, but I'd still restrict the focus quite a bit. From my perspective, a good undergraduate question should either deal with students who hope to become academics or with how academia works. I imagine that most requests for undergraduate advice would not fall into these categories, but some would.
You make a good point. For me, what I really want to avoid, are questions like: "I like this and that, what program should I choose?" or "shall I take this class or this other class?", I can see a lot like that on Reddit, and this is hardly generalizable.
I have the feeling that many questions asked by undergraduate students looking for a program are usually not generalizable, and that's the main problem. However, in this case, the question you mention is very general (how to prepare for university as an adult rather than after leaving high-school).
Is this site supposed to be for serious academics of graduate level and above, or not? The FAQ says that it is.
If we welcome undergrad questions, let's be explicit, (and anyone who wants a serious academic site, can go look elswhere). How junior do we go? Kindergarten and above?
But if we're sticking with the FAQ as it is, then let's close and delete all undergraduate (and lower) questions. On-topic vs off-topic counts for more than upvotes.
Candidates for closure as off-topic:
I "request to expand academia to include undergrad questions". I know that "Please do not bring undergraduate questions to academia. The Academia FAQ makes it clear that such questions are off-topic. They will be closed, and then deleted. Repeated deletions will earn you the suspension of your question-asking rights." You might "doubt that a new site is really needed for undergraduates, and this site appears to support a smaller audience than some sites." So if academia S.E. still doesn't want to "cater for undergraduates", I propose a new site http://area51.stackexchange.com/proposals/47320/undergraduate
