That's not the suggestion I give to non-technical users, that's the suggestion that I give to you that took the time to learn what OpenId is but complains about it.
What I tell website developers is to add a login with Google, Yahoo, ... + OpenId (Google and Yahoo are openId providers) and each will redirect users to the correct OpenId endpoint (the one from yahoo, the one from google or your own).
And I don't say anything to non-technical users. They will see a "login with Yahoo" or "login with Facebook" or "login with Gmail" and they won't even ask me questions about OpenID. The ones that know what OpenId is and have their own custom URL will use it. Others will use the endpoints provided by Yahoo or Google and won't know what OpenID is and they don't need to.
