You should provide an alternative to the "reply to confirm" over http. Just a link with the same secret. I find it easier to click those than to reply via mail, since I'm back at the originating application after I've clicked the link. Think I found a bug. After I received the "All set!" email I got this message when trying to create a list: "Please reply to the confirmation email we sent you. Only verified email accounts can create a list. " So, I'm basically unable to test the full application. But I loved what I've seen so far. More people should use minimalistic interfaces like this for their applications.
