Would definitely be cool to see more of the trust-metric info within 
advogato flow out in machine-readable form.

I did some prototyping in this area a few years ago (urk, many years 
ago!), http://www.w3.org/2001/12/rubyrdf/util/foafwhite/intro.html -- 
not so much the trust metrics side, ... just basic info about who you 
deem a non-spammer.

Kjetil, did you see 
http://www.w3.org/2001/12/rubyrdf/util/foafwhite/intro.html ?

Re mod_virgule, ... I guess a lot can be done simply with existing info, 
since we don't need to know how *great*, *wise* etc someone is, ... 
merely that they are not a spammer. For 99.x% of people, ... being a 
foaf:knows of someone else in the network is enough. But I guess 
spammers do have friends. The trust metric stuff would still be great to 
have, ... to help folk prioritise information, etc.
