Here is how to view your view your Foursquare check-ins on Google Maps.

1. Visit your foursquare feeds page. Right click and copy the KML link  (no need to download it).
2. Visit Google Maps and paste your copied link into the search box. Hit enter.

You can also add “?count=100″ (or any number that you’d like to see) to the end of the URL (after .KML) to see a specific number of check-ins.  About Foursquare also has some cool tricks on tracking your check-ins with Google Calendar and Google Earth.
