Sushi Etiquette

I'm not totally new to sushi but it's becoming something I eat on a semi-regular basis. I thought I had most of it down but The Sushi FAQ - How to Eat Sushi taught me a few things. For example I didn't know that "gari (ginger) is considered a palate cleanser and eaten between bites or different types of sushi. It is not meant to be eaten in the same bite as a piece of sushi."
