Hi all!
The help text says:
Tags are used to categorize discussions. Primary tags are like traditional forum categories: they can be arranged in a two-level hierarchy. Secondary tags do not have hierarchy or order, and are useful for micro-categorization.
That doesn't bring me any further. Can someone give me a concrete use case when I would be better off using primary and when secondary tags?
What's meant by micro-categorization?
Thanks!
