After you confirm who you are, you may log in.

This is the message that I got today when I logged into a new collaborative atlas site Platial.

Thank you, we have sent you an email to confirm you are you. After you confirm who you are, you may log in.

All sending you an e-mail and clicking on a link does is prove that you own that e-mail address.
User-centric services have for UUID’s (universally Unique identifier) linked to real people. I had a conversation with one of the lead technical people on this project and they are in a bit of a bind without being able to access third party identity servers. They don’t want to ask people for their login to Yahoo, MSN, Flickr etc. but services like Mobido do this and (young) people give them to use.
There now doubt in my mind there is a market need for these services.
