Well, the site homebrewzone.com does start with a homepage, which is pretty much mandatory for any sort of site structure. form there, the website really only has secondary web-pages that the homepage is linked to. I like o picture the website as a central page, with a circle of pages surrounding it, and that is what this website does.
Since it is a site that is fairly amateur, I don't think the lack of much depth within the site makes it deficient. It is not a site that you go to to become a professional brewer, just one for quick reference for the basic brewing needs.
All the pages allow for connecting to the rest of the pages, so the links are fairly well placed. The links could be organized a bit differently to create a more coherent site. I will be making categories labeled "Brewing for Beginners" Brewing for Experts" and "the brewing world" in order to organize the links. this will allow the user to kind of predict which link they will need to get the information they need and not have to bother with the rest of them.
