I'm a friendly, non-dev, cisgender guy from NC who enjoys playing music/making noise, hiking, eating veggies, and hanging out with my best friend/wife + our 3 kitties + 1 greyhound.
My day job is designing and developing websites, but in my off time, I like to build all kinds of things, including Ruby gems, iPhone apps, and Alexa skills.
So yep, your hypotheses is correct — works based on the published date!
Ahh yeah I figured... now I know for the future!
