I'll have to disagree. Many things about it are a constant source of annoyance for me, such as the fact that function arguments and return types aren't listed in a standard format with a short description of each and instead they expect you to read the entire (often quite large) paragraph of text below each function to find that information, and the fact that a lot of information isn't found in the page you'd expect it to be in (for example, the methods available for the list type aren't in the Built-in Types page even though lists are mentioned there, nor in its own dedicated list page, but are instead in a "More on Lists" section in the Data Structures page which apparently isn't linked in the types page at all)
