Someone needs to make a Persona Persona. We're our own worst SEO enemy :)
The Firefox themes were renamed to... background themes. It's just that the addons team (which owns getpersonas.org) has been hard at work on the new Mozilla Marketplace, and the Persona team has been hard at work on Persona. A few of the Persona devs are going to hack on this next month and try to get a disambiguation page deployed. We don't want theme-seekers to get lost, but we also don't want to lose people looking for the authentication system, so a straight 301 isn't ideal.
