Just before AOL and Digg blessed Open ID, Microsoft did too, so I talked to Kim Cameron about what it meant. A short portion of the conversation is on the Developer Register as Identity brings Microsoft and Internet 2.0 together.
But please, don't tell me things like 'I won't trust CardSpace because I don't trust IE' without A going and reading up on the security background of CardSpace 2 being prepared to tell me what you think the security problem is. Want to complain about Microsoft technology? Make sure you know as much as I do about the way this is designed (or preferably more and you can teach me something)
