I really like the idea of Persona, and it's very easy to integrate with your own site. However, it's still a bit unreliable. For example, clicking on the zonino login button just opened a mostly-blank page for me (white on the left, light grey on the right, with a pointy arrow in the middle; a bar at the bottom says "Mozilla Person...", but no way to log in. If I do "F10 -> View -> Page Style -> No Style" I see various boxes, but it's not obvious how to proceed. I entered my email into the top-most box and tried clicking the "next", "sign in" and "OK" buttons, but none of them responded (there's also "continue", but that's greyed out). I think I had the same problem when I tried it last year. Probably just some browser plugin issue, but would be nice if it were easier to debug... Works in Chromium though.
