When I migrated my forum from phpBB to Discourse, I decided not to use tags, convinced that the users wouldn’t use them properly, hence resulting in a half-functional tool, unless a staff user would constantly add themselves tags on other’s topics.
It was because I myself wouldn’t know how to properly use tags on some forums I frequented. I often would leave this field blank. I thought the title and categories would be enough and the search would do a good job with these two fields (+ the message content). I wondered if this or that tag would or wouldn’t fit.
It made me think about how to use this field when I just had to fill a title and content, which was a very familiar and straightforward thing to do.

What are your own experience using tags? Do your users use them properly?
(So to be a bit more specifical, my thread is more about your experience of using tags as users and admins than a discussion about tags usefulness)
