On: Darpa wants to make a better, more secure, version...

[SEJeff]

Yes, because there is an inverse relationship to usability and security. Signal won't add a feature until they can call it entirely vetted and secure.

>inverse relationship to usability and security

Not necessarily. You can easily have all kinds of shitty usability without it having anything to do with security.

An inverse relationship between better security and usability perhaps? More security == less usability. Look at PGP encrypted email as a shining example of security sucking for usability.
