A couple of days ago I've found a nice website that categorizes other website by geographical location.

It can show the neighbours of Guus Bosman.nl. Another site with the same functionality but based on Dutch zipcodes is LogMap.

Websites close to me are for example Een Scherpe Blik, Willy Boerland.com (in Santpoort) and Websnacks.nl (in Haarlem).
