So, this is something I'm still thinking about, what should go in AUTHORS. 

The AUTHORS file is used to set the authors for the gem.   Should the authors be the maintainers, the people with significant contributions, or everyone?  A common alternative is to have a CONTRIBUTORS file that lists everyone. I didn't create that when I added the AUTHORS file since I wasn't sure how I wanted to handle duplication.  Thoughts @robincurry @danmayer @MGotink ?  I could also ask @jscruggs how he decided to add people as authors of the gem.
