I just wrote a little hack to track your Google Latitude Location.
Enable your ‘Google Public Location Badge’
Choose ‘Enable and show best available location’ or ‘Enable and show city-level only’
Copy your user id (it’ll be a number like -77777777777)
Set up an automatic feed on Cosm
http://cosm-stalkr.herokuapp.com/location/-7777777777 # replacing your user id
Stalk me on Cosm
