Dashblog, written by June Tate, is a Mac widget, that allows you to blog to any blogging platform that supports the Blogger API, and in short, allows you to flick your mouse, press F12 (or however else you get to dashboard), type your post, and publish it to your site. No browser or other software required!

Since this site runs on Drupal, the Blog API is one of the modules supported out of the box, and therefor works easily with this widget. Handy handy!
