Tagging has grown up as a kind of "metadata-lite", ie a quick way of categorising blog posts etc into topics, often fairly broad topics. Of course it can be a very useful way of finding related material. However if you are able to say something more precise, then I think you should - eg by using dc:subject or foaf:primaryTopic, to say that a blog post (or other document) is about a particular thing that you have a URI for. You might also want to have tags of course, in their role of more general categorisation and the Common Tag ontology looks a nice way to handle that, especially with its capabilities for saying which user added a tag - so letting you handle an applicatoin like delicious.com.
