Bottom line, computers existed prior to Apple, but the Macintosh changed everything. Ease of use matters and is something that cryptography has not yet achieved.
Was it really Macintosh that changed everything? If I think of computer I think of "C64", "MS-DOS" and "Windows". Even if Microsoft stole ideas - those were the mass-products that changed everything, in my opinion. Just like Linux (not Unix!) changed everything later, again - in another way.
To stay on topic: Let me say first that I don't like the name "Keyhotee". Maybe for native english speakers it makes sense in a way... in many other languages it's just like "what?", unlike "Google", "Yahoo" or even "Microsoft" or "Facebook". - But ok, the name shouldn't be the most important thing about it (even if it kind of is if we talk about mass-appeal).
If Keyhotee will be as easy and idiot-proof as WhatsApp, the camera-app on Android or iOS, or even Google, and it looks good - it could become big, because everybody can use it no matter how dumb.
If it is free, open and really secure - it gets the nerds and techies, too. Hopefully.
Another thing is that "the first thing I see" when I google Keyhotee is "some strange company" creating a "just another" product. First thought "another startup wanting to become Facebook. Good luck. Next!" ...
Where is Keyhotee on Wikipedia? It has to be shown that Keyhotee foremost is an "open idea" in community hands, against surveillance, maybe backed by company money but still alive if the company goes bankrupt, and there will be no ads in it, ever, and no "pro-version" to buy. And a clear to see reason why to choose a new, not even born yet, product against "all the others".
If with Keyhotee (damn hard to type, too ;-) ) you want to reach something that will be pre-installed on every new computer and smartphone, you most almost reach the impossible. It's not always the best system that "wins", you have to reach "that certain something" to make it successful. (See for example
