Certain blog posts written by members of staff that are no longer with the company seem to be missing the attribution for posts that they wrote. For instance, JNat and animuson: workin' on ur problemz is blank in the "author" section, instead of showing that hairboat wrote it:
It did used to show the proper attribution.
Another example of a post missing the author is Stack Gives Back 2022, posted in January of this year (2023). It was written by Nicolas Chabanovsky but displays no authorship - in the past it displayed the author as "Nicolas Chabanovskii".
Some posts by former staff do show the authorship properly, though, such as A Day in the Penalty Box by Jeff Atwood.
While I don't know the ins-and-outs of the copyright and license of posts on the blog, the authors should still be displayed.
