The Great Font Hunt

My brother in law, Dougal has an interesting post about typefaces for webpages. ( http://dougal.gunters.org/blog/2007/07/05/typography-design-patterns-for-the-web ). You may have seen color charts for web page design, where it lists a primary color and other colors that compliment it. What Dougal is looking for is a similar chart for fonts. Anyone know of anything? If so post a comment on his blog or mine (or both!) and let us know.
