Michael McCracken: The read-once email client and reference emails.
"I’ve been dreaming of a new kind of email client, one that only lets you look at a new email once. That’s right - you get to scan it for 30 seconds and then you have to do something with it or it gets archived out of sight."
Michael wrote a script that'll take the currently selected email message in Mail.app, and stuff it in VoodooPad. Very cool.
