tags are great when you know what you're looking for but are terrible for browsing a new dataset.
this is especially true when you're the newbie eg on a project and you didn't have any input into the tag structure.

While SKOS was intended for more formal vocabularies, I've found its use as a basis for a tagging system makes exploration and navigation of a topic area reasonably organic, as it allows users to specify relationships only as they see as fit and intuitive.
