shit loads of easy to access documentation
Kind of true. But it's got a lot of flaws.
The examples are often overly verbose to the point of obscuring what it is they're actually trying to show, posted in VB, C#, C++, and every other language they can think of (and the language filter cookie seems to reset randomly).
There's a lot of broken links (perhaps not in the C# section though), and the link structure seems to change quite a lot.
It has documentation pages for every property of every class, most of which are completely useless and not worth clicking.
