It was a poor design and like the Soviet Union once the central plan didn't comport with reality, it had to die on the ash heap of history.
The idiot MSN Groups is what killed it for me. If you have multiple identities, multiple email addresses, and different ones are joined to different groups, you can't remember which identity is to which group. The idiot MSN implementation sends you emails from the group but doesn't show you the email address that the message is being sent to--your own email address.
So you can't figure out which one to use to sign onto the Passport and of course since you use multiple identities you don't want it cookified on you.
Then the necxt problem is that it won't let you even use it if your cookies are turned off. You'd think Microsoft would have figured with all their security problems that people will turn off cookies and ActiveX (they give you the function to do it in Explorer) but then their passport thing doesn't work.
I hated it and would join Yahoo Grpoups instead of MSN Groups and they have their own problems but not this really quite rudimentary level of stupidity.
