[OpenID] Social whitelisting with OpenID

[Simon Willison]

I've written up a proposal for an OpenID social whitelisting  
mechanism, whereby blogs can publish lists of OpenIDs that they trust  
not to be comment spammers. It's mostly meant as a demonstration of  
the kind of interesting things you can start to build once OpenID  
becomes more widespread.

As always, comments are welcome. I'm really interested in the idea of  
using OpenID as the basis for simple trust networks.

Cheers,

Simon
