"Earlier today, Ivanka Majic tweeted a link to the map
of where Ubuntu Servers are being used around the world and I
thought that was pretty cool so I wanted to find out a little more
about how this information was gathered.
"According to the website, the application shows Ubuntu logo
over each city where Ubuntu Server is used and the data is
collected through volunteers who visit the application and agree to
add their city to the map. Also stated on the site is the fact that
personally identifying information is stored in the application
database. Those who visit the application website can choose to add
their information using their IP address or just see where Ubuntu
Server is already being used."
