Not at all! This is an interesting and important question, and you are 
certainly not the only one who will face this problem.

So, these are fairly broad topics, and this may (or may not), make it 
somewhat easier on your side. I would like to point out that all the 
categories of Wikipedia are modelled as skos:Concepts. If you are fortunate 
enough to deal with only Wikipedia categories, I would do e.g.:

<http://yoursite.org/blog/he-could-do-it> dct:subject 
<http://dbpedia.org/resource/Category:Barack_Obama> .

In some cases, you may not have a good category, but I believe that in many 
cases, it may be just as useful to say
<http://yoursite.org/blog/allah-rulez> dct:subject 
<http://dbpedia.org/resource/Category:Politics> ,
<http://dbpedia.org/resource/Category:Iran> .
as a more specific category.

If not, then you may have to go into the extra complexity of CommonTag or 
MOAT, which may indeed be necessary in some cases.
