Comment To give email new life, you'd really have to... (Score 3, Interesting) 45
1. Guarantee privacy. This is something that Google et. al have been trying to wean the public away from-- wanting privacy. So many people simply don't think to ask for it any more. You can't do it just for those who ask for that to work. You have to do it for everyone.
2. Provide hard anonymity. One of the things that made email super useful and that we don't have any more is the ability to be reasonably anonymous. Law Enforcement or 'Public Firewall' officials world-wide have clamped down on the ability to use or reach the anonymous remailers we *used* to have. It's not just LEOs who will fight this tooth and claw, but also the 'think of the children!' types.
3. Enforce non-commercial communication at the user's request. Spam filters have gotten pretty good. Most businesses that want to contact you have to jump through hoops to get your okay. However, once you establish that one 'business' relationship, you're fair game. Buy one toilet seat on Amazon, suddenly you're deluged with 'Today's hot toilet seat deals!' and the like. You've got to dig through their website to find the 'unsubscribe me!' button, and a lot of the time it doesn't do what it says. The user needs to be able to turn commercial email on and off with a switch, and every 'rejected' email needs to get bounced back to sender at the mail exchange level.
One new webmail client or novel server configuration is unlikely to solve these problems. I do think that all of them are solvable, though, even though they'll require a great deal of re-architecting email.
Unfortunately, unless you can somehow invent a magic bullet that will keep world governments, law enforcement, and marketing types from ever being able to touch such a service, it won't stay usable long.
