Tag click counts

How to tell how popular your tags are? We have a total count of each tag, fine, but what if one or two tags are looked at more often than all the others. This is potentially fantastically useful metadata?

Discourse, has always had a great feature: link click counts.

I’m wondering if it wouldn’t be a great thing to maintain counts of clicks on Tags and display that statistic somewhere, perhaps on the Dashboard in a top 10 and on the Tag page?
