It's not just a coin it's a platform. Your going to try and tell me that encrypted messages, voice, and video that is totally decentralized is not useful? Hell it's a multi billion dollar feature. Do you really like the NSA collecting all your data, if anon is such a big deal I would also think that having an XC app on your computer or phone to chat, call or skype totally anonymous is a big deal.
tox.im already does this, and it does so in a way that cryptographers agree is reasonably safe.
Until we see a whitepaper detailing the cryptography and mathematics behind this anonymous, encrypted voice/video/chat it's nothing more than hype to sell a coin. Even when such a whitepaper is released (and please don't link me to whitepapers with walls of text and zero maths) it will have to be vetted and peer-reviewed before it can be considered excellent or even safe to implement.
First you plan, then you talk, then you publish a whitepaper, then you write code, then you release. Not the other way around.
