Interesting site with lots of good information, but a lot of it seems to be possibly done by data mining. All of the Frank Ford tools really just re-direct your browser to Frets.com. When you click a phot notice the re-direct URL at the bottom. Several other items I checked did the same thing, linking you to Lumberjocks, woodgears, etc.
It is useful to use as a search engine, since the photos are displayed and might alert you to a site that you were unfamiliar with.
