tl;dr: We are removing Disqus comments from the AngularJS docs.
Problems with Disqus
Besides making it difficult to moderate off-topic or inflammatory comments, many comments are specific to past versions of Angular. We think the documentation should be versioned alongside the code so there's never a question of whether information is out of date.
Disqus has been great for allowing us to get feedback and allow developers to share tips about AngularJS, but we think there are better ways to do this now. You'll always be able to see the Disqus comments in past versions of Angular (<=1.2.2), but going forward, here's where we think the things previously posted in comments should belong:
Post questions to StackOverflow or the mailing list. They tend to get answered more quickly and stay up-to-date because of the active community there.
Bug Reports (Issues)
Bug reports should go on Github. It's useful to be able to see everyone's issues, workarounds, and the progress towards fixing them all in the same place. See the relevant section of the contributing guide for more.
Improvements to the Documentation
We think the best way to improve the docs is by directly improving the text. You can do this via the "improve this doc" button at the top of each page.
