Blog URI, is it necessary?

An OpenID server is vouching for the person using the browser, asserting 
they own/control the input URL.

Alice needs to provide a unique URL that she has implied control over. 
This keeps a 1:1 mapping between a URL and a "user." LiveJournal can't 
go around asserting for everyone.

However, this is not to say, a site (Craigslist for instance) can't 
piggyback OpenID on top of its anonymizing code and provide its users 
with an anonymous URL that can be asserted without tying it to an 
individual user:
