Alan Wolk: Everything Is Great Until It Isn't: " has turned the spotlight on companies who are seeking to remedy this through something called “persistent location” which broadcasts your whereabouts whether or not you have the apps on your phone open. The advantage is that it can track you as you move about your day, so you don’t have the lag time of the smart phone figuring out that you’re 10 miles from where you last checked in every time you open the app.
That’s also the disadvantage: the companies building this technology are also billing it as a way to push coupons at consumers when they are in range of your business. So if you are, say, around the corner from Starbucks, you’ll get a message inviting you to have a latte for 25 cents off."
