Agreed, I dont believe that either quite the opposite truthfully, Its
the way UID is being used in microformats that is troubling me A huge
amount of published hcards that I have seen are almost exclusively
using url+uid which leads me to the assumption. that is the only way
to use UID in microformats which I don't believe is true but no one
seems to say any different.

That is something I cant determine yet there are advantages If you use
OpenID url's but that doesn't happen very much.
I believe PURL's should be promoted as URL's that can also be UID's an
Author can guarantee global uniqueness even if 10 different purl's point
to the same address or an Author changes his website from time to time
because the purl will never change.
