John’s posterous

Intriguing, where does posterous.app come from?

I made it in about 2 minutes, about the second time that I've used Automator which should indicate its simplicity.
What you see above is about it:
New Mail message, posterous address, from address set, options, ask for subject;
passed to Send out going message.
Save as app, drag and drop files to post.

Got to give it a try. Thanks!
