Anthony's account URL does not have a direct ID, but if you mouse over to Anthony's user name or copy the link's URL, you can easily see that the ID is "114756468015607312300".
If you look at the ID in the source of the Google + page, IDs are written to the source in the form of "id =" (Anthony's ID) "or" oid = "(Anthony's ID)" I understand.
