What advantage does Signal protocol have over basic public key encryption?

I clicked the URL in your first email - the second one worked - as did a Google search.

So, onto your query - I understand " Coderpunks " answers the more technical questions.

Have you tried them?

My knowledge of Signal is colored by my impression that Moxie Marlinspike can't be trusted.

He quotes Marx approvingly. Goes MIA for decades. Does fluffy interviews with the shitty likes of Joe Rogan and Nuclear Wintour. 

Why I call him " Poxie Fishook ".
