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.
"Strategic" voting is pretty much unavoidable, since voting has some cost (however mild). It makes sense to vote when you think it will make a useful contribution, by expressing a different POV than other LessWrong contributors would. Does this make scores less representative? It's not clear that it does - how many people would care if some unambiguously good comment is at, say, +17 as opposed to +19 because some users just didn't bother to vote it up?
