Show that person an OpenID login and ask them to figure it out.
10 times out of 10 they will give up and either A) create a new user ID without OpenID, B) not register at all, or C) use Facebook Connect.
People seek the path of least resistance. The average person does not see a tangible benefit to OpenID, and it's easier to ignore it than to take the time to figure out what it is or how to use it.

Show that to your aunt, and see what she does when faced with that page.
* No support for iPhone/Android/etc apps
* Users may be firewalled in, without access to google.com, etc
* Facebook does not support OpenID directly
* All users would be working for a particular org who is not an OpenID provider
* Not all providers support discovery yet
* Hybrid approach feels wrong for new websites,
but so does making users sign up for an account
with a third party first
I use it for my own accounts, but don't recommend it to others yet.OpenID login can make logins possible with two clicks, and it is possible to use a hybrid approach.
