I consider myself a reasonably savvy internet user. I try to be careful about what I put online in the public view and what I keep private. When I was offered the option to turn off location tracking in Google, I did so. I only rarely post information about my whereabouts, and when I do, the timing usually doesn’t match with when I was there. So when people started posting links to the Google location tracking page lately, and showing how scarily accurate their location was being tracked, I just wrote it off as silly people who didn’t turn off location tracking in Google. For some reason, I decided to click on one of those links after seeing veteran WordPress developer¬†Ajay D’Souza posting about it on Facebook. I was stunned to see a scarily accurate plot of my exact location published online by Google!¬†I’m not sure how that happened; either Google screwed up, or more likely, I turned off location tracking in one place, but not another. For an example of how accurate the location tracking was, below is an exact map of a run I did in Oslo on September 15th 2013.

You can see how well Google is tracking your own location via their location tracking page.
