Dwolla is equally involved in this identity thing, the difference is that they are cloaking their approach in the "isn't it cool that we can now interact with you through Facebook" line of bullshit. Same intrusive back-rape, same demand for access to your privacy without justifiable cause other than to make them a better buyout target, and to provide them with data to whore out to other companies for big paydays.
And no, I don't work for Gox, or Dwolla, or any other entity that has been described in this community. Or consult for them. It's just pure my attitude and experience in the world talking.
