Groklaw is a good contemporary example of handling the second example, I think. But in both these cases, it takes time for the word to get out to peers and experts, and for their contributions to filter back. Can Semantic Web technologies help to reduce the time and increase the exposure to that distributed knowledge? I haven't seen discussions along these lines so far, except to say in a generic way that the involves some "web of trust". That's too generic to be useful.
