Update 6/28/16: Facebook has backtracked and said that it does not use location data. The confusion supposedly arose when Facebook tested a location-based People You May Know feature, but that test had ended.
You probably know your phone can pinpoint your location for GPS, local search, or the weather. Hopefully, you also know that means your phone keeps track of everywhere you go, all the time. Don't be alarmed—it's the trade you make for the features you get. If it makes you uncomfortable, here's how to opt-out.
Next time you check in at a local coffee shop you might see an ad. As expected, Foursquare has just rolled out ads to its mobile apps.
Your iPhone knowing your every move without your knowledge and without function: bad thing. Your phone knowing your every move so that you can share it with friends, receive geotagged reminders, and keep track of travels: very, very cool.
Is Facebook Places not sufficiently immersing you in the mundanity of your friends' lives? Try Nearby Friends, an app that plots their check-ins—past and present—on Google Maps. Just don't let any of them catch you using it.
Will most people ever really aspire to be mayor? The buzz surrounding location services is massively disproportionate to their actual use, says the NY Times—only 1% of Americans use them weekly. But will it remain a yuppie novelty?
