Show HN: API Changelog

The past few weekends I've been working on a side project called API Changelog. The site monitors the API documentation for 23 popular services like Facebook, Twitter, Dropbox, etc. When the docs change, it sends you an email. I review all the changes to make sure that typos and other non-material changes don't get through. It's free (sponsored by the company I founded). Would love to get your feedback! https://www.apichangelog.com Example recent change on Twitter: https://www.apichangelog.com/changes/49330b17-bd84-47a8-86eb-b691061420c5
