One of my favorite things about the old kitchen table math site was the index. The book index is a brilliant invention; Google doesn't come close. After the first ktm froze, we moved to Blogger, and I've missed the index ever since.
Now I've got a new one.
Actually, Blogger has been offering the option of creating stand-alone pages for a while now, so I could probably start putting together an index for ktm, too.
In my spare time.
