I'm afraid I have to strongly disagree with your opinion (rant) on Mathematica's documentation. Though the docs are still not perfect, I usually find within a few clicks what I'm looking for. I'm actually rather fond of the documentation as it is now. The mixture of overview pages, tutorials, function doc pages, crosslinks, and the fact that doc pages are 'active' is very effective in my humble opinion. Access to the docs in function browser, book, and doc centre form is nice as well. Navigating around is extremely well done. There are some lingering issues, such as the occasional lists of "typical" option values listed on some doc pages instead of listing *all* possible option values, and the use of the same option name in completely different functions (like "Method") which often makes looking up the specific option doc page useless. And indeed, some options are only explained in the examples instead of on the formal section of the doc page.
