I usually use MarsEdit for posting to this and other blogs, but that means I always have to log into the web GUI and manually tell the Drupal Twitter module to send a notice of a new post.
After digging around for a short bit, I discovered that I might be able to automagically do this with Drupal Triggers.
This post is a test of that functionality while posting via the web GUI.
Thank you for reading this non-emergency broadcast test.
