This is a great idea and much more aesthetically pleasing as well as practical. I assume the carousel would be structured with the most recently pinned post being displayed in the first two thumbnails which are visible by default?

It would be awesome if there was a way to separate pinned from perhaps "highlighted" stuff... Like pinned being critical and informative community related stuff and "highlighted" simply putting eyes on certain users posts for a limited time...

Either way - this is still a MASSIVE improvement from having to scroll for eternity through a sea of pinned posts, which yes - just like you, I barely even look at anymore.
