How are you using tags?

[AndrewSimm]

Since 2011 I have opened two boards that have a combined 10 million posts, but in the same period, they have a combined 0 tags. In fact, I have never allowed users to utilize tags. I never saw the point in tags and have always tried to keep the boards simple. Now, I expect a lot of successful boards do use tagging, so my question is, how do you use tagging and what have you learned from your experience?
