I like the general idea of making email a human api for web services.
Email based invoice generation service, markdown renderers, tweet/blog from email, post to forum etc. seem to fit into this category. Services like event/reservation booking can also be used from email if the service has a forgiving parser (like WolframAlpha) for the human input.
I agree. We've been thinking about email as an interface for a while now. It's the most accessible interface. And every once in a while there's a discussion on HN about this. So I guess this acts as proof of concept.
