Although Unix & Linux has gotten rid of the 'for advanced users' part of its description, it still comes across to me as a site for advanced Unix users - perhaps just server admins, even. This recently caused me to create the Debian Area51 proposal, which I now accept is a dupe of this site (well, a subset anyway). But it led me to thinking: is there a way that U&L can better brand itself to indicate that it's open not only to advanced users and server admins, but also new-to-intermediate users of all Linux distributions (except Ubuntu, of course!) I'm not sure exactly how to do it, but if you Google for "Debian Q&A", it would be nice if this site came up at least in the top 10. I don't think it's very 'discoverable'. If you're going to welcome beginner questions about all distros, the look-and-feel of this site right now doesn't feel appropriate; it feels very "command-liney". ;-) These days, new users of Linux will almost certainly be using a GUI, alongside a commandline.
I don't think the look-and-feel, or arbitrarily matching "Debian Q&A", is the correct way to think of this.
If you want to attract (quality) beginners, make sure there are a lot of quality beginner Unix questions on the site! That is what will lead beginners here in the first place.
Therefore, if you want to make this site more hospitable to beginners:
Ask (and potentially even self-answer) lots of great beginner questions. This has to happen first; we can't expect beginners to magically materialize without a corpus of good beginner Q&A pairs.
Generously share links to great questions and answers wherever new Unix users tend to congregate.
Love and reward your newest users for being awesome!
