It's available to any user with an email address -- you don't have to limit yourself to users that have, and are willing to use, a Facebook or Google account.

Versus rolling your own, you don't have the friction of account creation / password management for new user signups if the user has ever used Persona before, and we'll be dramatically improving first-contact before the end of the year. You can completely forget about storing passwords. You don't have to send email verifications or handle forgotten passwords.
