David Feldman of InterfaceThis has released an awesome and easy to use tool called Zoodo. Take a look, it lets you create tasks and then set a due date using natural language. I can imagine doing something like this in Flock and then hooking it up with Backpack or Remember the Milk. Man, would that be cool or what?!

Chris, over at Remember The Milk we already have a bookmarklet called Quick Add that works the like the Zoodo tool — it accepts due dates using natural language in a very similar way. I agree that Flock integration for something like this would be very useful.
Chris, this is completely off-topic but I can’t resist it!
You have to check out this cool terminal app for OSX:

Let yourself go back to the 70’s in an amber or green glow distorted monitor! Enjoy!
