What Jamie wrote
This seems like a really cool service. You send an email to your diary and then this service keeps it private and secure for you. It’s a very simple way to author. It also has a newsletter like extension of allowing friends to subscribe to those notes you send. I’m not sure about this being a black box, I'd want to know there is a way to always keep a copy of my data, but the user interface being simple email is good.
