Realtime messaging with a simple link. No sign up required

It sounds wonderful, but I have just so many questions. No doubt they don't want to tell us how it actually works, but without knowing that, there's no way I'll trust them.

It's very much a chicken and egg. They say that privacy is what's driving the design, but without knowing how it works I have no way to verify that it really is what they claim.

Tricky.
