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.
I do have something specific in mind (about how plant physiology is often divorced from population research), but I am in a minority here, so it might be more interesting for most people to read about other stuff.
I, for one, would be interested in such a post.
