What happens when you switch various OpenID IdP’s?
Your OpenID keeps changing.

What do you do if you do not have your own website to ensure the your OpenID remains constant?
You should use Permanent OpenID.

Using the Permanent OpenID, you always use your OpenID as www.jkg.in/popenid/username irrespective of the OpenID Identity provider you use. We recommend that you do not use a Anonymous OpenID unless you are sure of its implications.
