I’m not a big fan of pinned topics to be honest. I feel they are a misused Forum-Way of collecting FAQ and category description (which is exactly the way we are handling them here, too). Both of which might be important to the novice (not logged in and/or trust-level-1) but are mostly annoyance to the advanced user and take up all this great top-space for so many lists. And though I’d personally loved to see a category-banner-topic like the application pin banner (including the dismissal feature – oh, yes please!), I think the least we can do is let a category to be configured to not include all it’s sub-category pins.
Here on meta we don’t have any category that has so many subcategories that it ever matters but on our forum here, where every local group gets their own sub-category (so you can more easily mute non-relevant content) and a growing number of that is very much wanted, the growing number of pinned category descriptions are just a pure pain:
I have no relevant content above the fold here. Though it is a great meta-category to see what is going on in each chapter. But with four (and potentially more) pins, it is a completely useless view. Can we please have the option to exclude sub-category-pins for a parent category?
(Not sure whether this is supposed to be in UI/UX or features. You decide).
