If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Feel free to comment -- since only the user you're replying to (and anyone that has chosen to subscribe to updates for that specific post) is notified, you don't need to fear being a distraction to masses of people who might no longer care.
It does also show up on the Recent Comments view, which is one of the most common ways for people to jump into discussions. So it'll be noticed by other people as well. (Which is good, if they want to also chime in.)
