Which makes orientation extremely slow, confusing and frustrating. Example: we have a user who wants to know how to upgrade his gentoo system. He knows precisely the topic he's looking for - "upgrading a gentoo system". But what he's presented with is a bunch of artificial, bureaucratic categories like "FAQ", "Home", "Listing of Documentation", "Installation vs. Documentation", "Gentoo handbook vs. installation docs". Some of them are even incorrect - Gentoo Handbook is in "Installation" section, although it contains information not only about installation, but also about system running. If the questions he has to answer is "installing vs. maintaining", "system vs. individual applications", "general usage vs. troubleshooting", then he could answer them and select links appropriately. But because the web is badly designed, he's supplied with questions he cannot answer. There's no way he can tell from "upgrading a gentoo system", if he should choose "Installation - Gentoo Handbook" or "Documentation", if he should choose "Home" or "Listing", if he should choose "Gentoo linux forums" or "Gentoo Linux Resources" (documentation is a resource, right?) The result is, that he has to scan the whole website. Even worse, as there are cycles in the website, he needs quite a big amount of memory, because he cannot do it with DFS, but has to use BFS, which requires longer FIFO que and not a small stack. It means that for every trivial problem he spends ages searching for the answer. I propose this structure, which is just an artificially constructed problem from the user's point of view, to be replaced by a natural structure according to topic - a structure, where every time the user knows where to click just based on what he wants to know.
Your input is certainly welcome on www-redesign mailing list, bugzilla is not an appropriate place for such discussions.
