Identoo
Mark Krynsky is excited about the potential of NoseRub . I don’t disagree, but I think it is creating a market problem as I am not sure whether Identoo or NoseRub is the proper name for the service at this point.
The site is also displaying a number of errors as of this writing and several service feeds I tried to enter failed. I am sure those are just momentary errors, though, and I will revisit this paragraph a little later. And I can’t be too down on any service that supports OpenID.
