I don’t see any value in this. There are tons of news threads throughout the week. Adding one more, but pinning it, is the only goal of this? And it’s to ensure we get at least one new thread a day? If it’s a really slow day that will force the “nominee” to come up with something, anything. Doesn’t the engagement in a thread already tell us the popularity or interest level in that topic?
All of that said, I - and anyone else who doesn’t like the idea - can simply scroll past one new pinned post.
Candidly, I tend to skip over pinned threads on any message board; kinda like skipping the paid results after using a search engine.
