Change "Category" to "Author" on Homepage Grid

Hey all,

I would like the “category” links on my homepage grid to pull from my taxonomy of authors as opposed to my taxonomy of categories. Is this a possibility? Having a few issues when tinkering:

1. I see that this can be changed on the content-featured-post.php. Specifically the line: <span class=”cat-links”><?php echo get_the_category_list( _x( ‘, ‘, ‘Used between list items, there is a space after the comma.’, ‘twentyfourteen’ ) ); ?></span> . What do I change this to, and how do I do it in my child theme custom CSS editor so that I don’t destroy my infrastructure?
2. I’m using this Byline plugin: https://mattdulin.com/byline/, and would love to pull from my byline taxonomy instead of author taxonomy if at all possible. Tips, or is this an impossibility?

Thanks for your help!
