I'm experimenting with adding geographic metadata to this site. The home page now has additional meta tags to enable geographic searching at GeoTags and GeoURL:

<meta name="ICBM" content="52.422400,-0.803000" />
<meta name="DC.TITLE" content="Internet Alchemy Weblog" />
<meta name="geo.position" content="52.422400;-0.803000" />
<meta name="geo.region" content="GB-NTH" />
<meta name="geo.placename" content="Rothwell,  Northamptonshire, United Kingdom" />

These tags can, in theory, be used to pinpoint the geographical focus of this weblog, whatever that means. It might make more sense to add it to my FOAF.
