> Open ID failed because you couldn't explain it to your grandmother. Counter example: XMPP/Jabber. People who use Jabber can talk to each other with no problems.

Put someone's address in your email program and it just works. Plenty of people run their own email server, despite them being notoriously complicated to set up.
