Hi lifeisstillgood, I am one of the core Persona developers. Persona is a pretty awesome project with very ambitious goals. We obviously want to see growth explode and are working hard to make Persona great for both users and site operators.
Persona's growth has been steady, primarily driven by newly developed sites. We hope that as the user base grows and support for the BrowserID protocol is natively built into the browsers, existing sites will have more of an impetus to offer support.
A version of Persona is already integrated into FirefoxOS and we hope to offer support in desktop Firefox by the end of the year.
In some downtime at work I threw together a rough proof of concept just to see what it invloves in go[1].. It was crazy simple to get running. I hope people start using it in more places.
Mozilla uses django for many of our web apps, and there's a django app that integrates Persona (formerly called BrowserID). Take a look at the repo, and if you have questions, ask in the #webdev IRC channel mentioned in the readme.
