When I went for my gap year travelling Central and South America for a year, I made myself an Android app to send my location to facebook over data or over SMS. Those were the times, when facebook still allowed status updates through SMS and more importantly to get one's status feed in RSS to further process and display on a map (two features now unfortunatelly discontinued). This allowed me to display here almost real time how I travel even through parts of 3rd world where wifi or mobile data did not reach yet (one feature of 3rd world which is also almost discontinued). Partly discontinued it might be, but the map above nicely preserves the overview of the whole trip. And you can read more than 50 stories from this travelling year on my blog.
