Found this quiz via Jason Kottke: How many HTML Elements Can You Name in Five Minutes?
I got 47 out of 90. Oddly, CITE was the first tag that came to mind, although I don't think I've ever used that tag in my life.
Some of my embarassing omissions: TITLE, BLOCKQUOTE (which Kottke actually mentions in his post about the quiz ... duh), and, ironically, CODE, which I used to semantically mark up the tags in this post.
