From bug 723011 We really need a sort order that is by date of original post which will make paging through threads easier and avoid missing any as other contributors are commenting and bumping stuff up. Do not change the default post date. This is just the backend support (i.e. adding support for the additional ?sort= parameter).
By "default post date", I meant "default sort ordering".
Done in https://github.com/mozilla/kitsune/commit/953a77a. Add ?sort=created to the url and it will do the sorting by question creation date rather than default.
Verified able to update view to sort by created date using the ?sort=created to the url
