It sounds like a good idea, but if there was a section for beginners questions, the older posts would still be out of view, so the questions would be repeatedly asked as usual. People would either have to display all posts from the beginning of the section, or use the search option.

I want to start my own site eventually as I don't think there's 1 site on the net that coveres the sort of things I'd have wanted when I started the guitar.

That's too complicated an issue to go into, especially as no one would want to hear it :D

But yeah, the beginners section sounds like it's worth a try.
