Can we make this thread effective for both debates to reduce clutter on the board?
Nope.
1. The morning debate thread won't be stickied until after this one is unstickied, so there wouldn't be any clutter from too many threads at the top of the page.
2. One more thread on a board that already has over 5000 threads won't really cause much clutter at all.
3. Having two different debates in one thread
would cause plenty of annoying clutter, especially for people talking about the debates after they've ended.
