Simply put, the best way for a SE site to answer questions from beginners is for beginners to ask them. However, SE sites make for great Q&A sites, not for great reference sites.
Shog9 said when Hinduism.SE's private beta was extended:
Original content; more than just a Hinduism primer
There are a lot of questions here that are... Pretty basic. "Could be answered by a Wikipedia entry" basic. Questions that require no expertise aren't a particularly good way to attract experts. You gotta expect a few of these, but when every other question can be answered by a Google search...
...And worse yet, an awful lot of them are answered that way: by quoting external sources. A site that just regurgitates things that others have written isn't much good; answers like that just clog up search results without adding anything. It's important to cite your sources, but just as important to demonstrate knowledge of both the question being answered and the topic itself - this is where we can actually make the Internet a better place, demonstrating how to use this knowledge to answer specific questions. Answers that are primarily copied from Wikipedia or other forums / blogs - even when properly attributed - are just speed-bumps, annoyances to folks searching for good information.
I'd really like to see more questions that require some serious research and experience to answer... I know some of you have been studying these topics for years, and are well past the beginner stages of your education - what sort of problems do you encounter?
I do not mind beginners asking beginner questions. I do not mind experienced people asking beginner questions because they have a gap in their training or education.
Those are earnest questions that embody what a SE site does well. In the meantime, we want to attract experts–experts asking expert questions is one of the big things that predicts the success of a SE site, in part because success is defined that way–so it is best to focus on questions you are or have struggled with or you see someone struggling with (though asking them to come ask the question themselves is best).
