I want to kill email, by replacing it with something new. I don't want incremental improvements or altered workflows, but rather a new technical underpinning that lets people continue to write long-form messages to each other. I have much grander ambitions for the company later on though, so I don't want to lock myself in with some company name like NewMail, Inc.
