Presumably you can strongly encourage people (e.g. in the FOAF docs; I haven't looked) to prefer pages from e.g. Wikipedia over some arbitrary even if apparently canonical page.

Besides, what's wrong with saying, without using another URI: <http://en.wikipedia.org/wiki/Resource_Description_Framework> foaf:topic _:rdf . <http://www.w3.org/RDF/> foaf:topic _:rdf . ? Another concern is the drift in meaning of assertions you'll get using something like Wikipedia to provide a "controlled" vocabulary. When I assert _:me foaf:interest <http://en.wikipedia.org/wiki/...> . I really mean I have an interest which is described by that page at the time the assertion was made. Probably not such an issue in geek space with well defined technologies.
