I think that is a very interesting observation. I kind of had that 
feeling, but is interesting to hear that you have actual experience to 
back it up.

I think topical trust is a very interesting field, and one that the 
Semantic Web Community should and is addressing in many interesting 
ways. Widespread use of it is something I think will have to come as a 
consequence of applications creating compelling reasons for people to 
use it, applications that depend on people creating explicit, topical 
trust relationships are not very likely to succeed.

That said, I think that as we go, FOAF-based whitelisting can possibly 
create incentives to create context-sensitive trust relationships.

OK. I don't have any strong opinions. I'll gladly drop the negative 
scores if you think it won't be useful.
