Are you calling my old dad, with his yahoo account, or my other colleagues in marketing with live/hotmail accounts "tech savvy"? What a about my Hungarian relatives with freemail or humail? What about fastmail? People on HN are terrible with email. How on earth is it possible to think Gmail is the only option for email, a decentralized, standardized service? How ignorant do you have to be to make that assumption?
