Yesterday, Strava <https://en.wikipedia.org/wiki/Strava>, a social
network that collects data from devices with GPS, uploaded a heat map
<https://labs.strava.com/heatmap/#6.06/39.14391/35.00835/hot/all> of its
users around the world to the internet. Intelligence services are now
combing that map for data about hidden military bases and other tidbits.
It’s apparently not just fitbits, but mobile phones and a lot of other
devices.
