For a book, the Preface is roughly equivalent to the About page for a Website or Blog. And since this site is being organized a bit like a book I am calling this page the Preface.

Although this site does have a blog component that records thoughts as they occur (and displays them in the usual reverse chronological order), the main body of its content here will be organized by topic and accessible via the menu on the left.
