So, a lot of people complain about AngularJS's documentation, not just this article or the comments, but everywhere.
Does nobody see the bright 'Improve this doc' button at the top right or something? It's an open source project - instead of complain, contribute! The link immediately opens a github pull request for your convenience and you can edit it in github's own editor.
Yeah, you could shift the blame to Google, but afaik, it's not one of their supported products, but a 10% time product - meaning that the creators / maintainers themselves can't work full-time on it either, and rely on the open source community to help them out.
Go forth and fork.
