A lot of us have invested a lot of time learning Angular, pains and all :) . I've contributed to the docs, as well as source. I've also reported issues, big and small.
The current docs have come a long way from their previous state - I recommend people try taking a look at them now. The developer guide & API docs have gotten huge improvements within the past month! I think the only things that are really left is to recommend some best practices with examples and more examples in the API section.
It's one of those nasty problems, like the influence of money on politics, or gerrymandering, where the people best able to fix it are the ones least likely to think it's a problem.
