Note that I said that single signon *itself* was overrated. If you use
the same token to authenticate to multiple sites (and here the 'token'
is the email address) then your identities on those sites are ipso facto
associated with each other. *If* that email address is also never
leaked (never displayed, even to other signed on users, all communication
with the site encrypted), then you only have to worry if the
sites exchange information about their accounts, or if the government
comes knocking on their doors....
Yes, I'm paranoid. That doesn't mean they aren't listening.
That said, sometimes you *want* identities to be associated, so I'm not
saying Persona is a bad thing. Just that single signon is overrated.
