I’m going to start pinning some more topics globally on meta to see how that works out, to highlight topics that are especially interesting/timely. I’ll aim to not have more than three topics pinned globally at a time, I promise!
At the same time I am changing the site setting so pinned topics are not automatically unpinned when you reach the bottom of them. This will make it easier to find your way back to pinned topics should you want to do that. To unpin them manually, select the pin icon.
