Being a bit of a pedant, I do not like to use the skos matching 
relations unless I can already see that the resource I am linking my 
concept to is of rdf:type skos:Concept, skos:inScheme to a concept 
scheme, has a skos:prefLabel and preferrably at least one 
broader/narrower relationship. Unfortunately this means I rarely use 
matching relations to anything other than skos resources that I have 
created myself ;-). In the real world Im not sure this makes any 
difference, and the Semantic Web will probably survive either way, but I 
think it gives other people more confidence in your vocabulary modelling 
if its clear some care has been taken.

DBPedia asserts no skos relations for any resource I have seen (which is 
not necessarily a bad thing, and I havent checked everything), and so in 
the absence of anything more specific, I just link from my concepts to 
dbpedia with rdfs:seeAlso, which "is used to indicate a resource that 
might provide additional information about the subject resource", so for 
example, its rdfs:labels or rdfs:comments might be useful to a semantic 
web application, but do not expect any directly relevant skos 
relationships that it could do skos things with.

Cheers,
Andrew
