[OpenID] Financial-Reputation services model?

[SitG Admin]

There are already multiple sites offering to rate products and/or 
sellers, most of them filled with empty pages asking you to be the 
first to submit a review. I often wonder how we know that the 
feedbackers are authentic. Did they *really* buy that product? Did 
they *really* do business with that seller?

Credit, debit, check - money order? Unless we send an envelope full 
of cash, it's a fairly safe bet that our financial institution was 
overseeing the transaction. Could they selectively assert that just 
one transaction took place, without revealing any auxiliary details 
such as other purchases that the customer made at that company? 
Quality assurances might include such metadata as "This was the ONLY 
purchase made." and "A refund WAS issued." (or "has NOT yet been 
issued").

Start with one site accepting OpenID, and use SSO to stand out from 
all the existing sites with an accumulation of such user-submitted 
content already. Encourage other such sites to incorporate OpenID, 
and, soon after, utility-coders will have added ways for users to 
simultaneously update all such sites (much like utilities exist now 
to keep multiple blogs current with one another).
