1. find out where you are

if you do not have a GPS mouse or tracker, use http://www.multimap.com, they show the current GPS position somewhere on the page during scrolling.

then enter this here and verify. Then mingle a little with lat/lon until you hit home.

2. Paste to your foaf file:
in the header:
xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#"

as data:
<foaf:Person
 foaf:firstName="Leo"
 foaf:nick="leobard">
 <foaf:based_near>
  <geo:point geo:long="7.7667" geo:lat="49.4412"/>
 </foaf:based_near>
</foaf:Person>

3. upload foaf file

4. add the lat/long to your homepage

<meta name="geo.position" content="49.4412;7.7667">
<meta name="geo.placename" content="Kaiserslautern">
<meta name="geo.region" content="DE-RP">
5. Ping geourl

read this: http://geourl.org/add.html

then go here: http://geourl.org/ping/
and enter your web url

6. Enjoy

when everything works, you should go to your foaf explorer and see your homepage as being near you, like here
which leads to a geourl link (below) and other nice map links.

If you installed the firefox nearby plugin then you see cool stuff on the geourl page...

the nearby plugin will open allthegoodness, which is another great site.
