I have two things. A bug and a wish.
Bug: If I input cyrillic letters (probably all non-ascii unicode), it works in the post, but gets scrambled in a quote. One recent example (and the original post that was quoted). That worked fine last year.
Let's try it out: What happens if we quote öäüß Хорошо lỗi 오류 ขอให้เป็นวันที่ดี
And a wish: in bet threads the graphcial representation is based on the number of votes, similar to polls. But it would be more interesting to base them on the amount betted.
