Peter has a large enough user base that I consider it roughly 
representative of the global userbase (a rule, not an exception). We 
don't know the exact percentage but we can be reasonably certain that 
(as an absolute numerical amount) it's more than just Peter's users 
here. This sort of thing hinders adoption, and that makes it "our" 
(as in, the OpenID community's) problem rather than "Peter's" problem.
