Most importantly to my readers, I’ve migrated API Design Matters off of Substack (because, Substack). So this will be my last post on apidesignmatters.substack.com. But not the end of API Design Matters!

API Design Matters has moved to its own domain name:

apidesignmatters.org

The most important change affecting my readers is to watch apidesignmatters.org, as new content will be published there instead of on Substack. In leaving Substack, I will lose the ability to email all my subscribers when I publish new API Design Matters content. I will post on LinkedIn and Fosstodon (Fediverse) when I write new content, and use the hashtag #APIDesignMatters (Note: I chose to not use the social media platforms X (ɹǝʇʇᴉʍʇ) or Facebook.)

I already have two articles to entice you to apidesignmatters.org - a reprint of a Nordic APIs article I wrote a couple years ago:

Meet Hyrum and Postel

and my recent guest appearance on on Behind the API, hosted by Shane O’Connor:

The Reality of API Programs

I’ve updated all the archived API Design Matters pages here on Substack to link to the corresponding pages on apidesignmatters.org. You can directly view all the API Design Matters articles in the Archive.

Thank you for reading API Design Matters here, and I look forward to seeing you on apidesignmatters.org!
