I want to see what categories you over-use and under-use. You can see topics and posts made in a category on your profile page (instructions below). I personally have the most topics in #meta and the least in #features, and the most replies in #general and the least in #features. I have absolutely never used #thirdparty.
Instructions to find your most and least used topics:
Click on your profile, then to summary, scroll down, and then you’ll find it!
(I’m just interested😉)
