It was only a few of months ago that Facebook unveiled Places, its way of letting you check in to wherever you were, letting all of your Facebook friends know where you were hanging out. And now they're killing it off.
Essentially, Places never really caught on because anyone interested in checking into places was probably already using Foursquare. You could see Facebook's axing of Places in one of two ways: either Foursquare is so popular that there was just no point to Places, or geolocation apps are just not gaining popularity enough to warrant throwing money at them, and the outlook isn't great for Foursquare. As a former Foursquare user who stopped checking in places when I realized there was absolutely no point to it, I lean towards the latter, but we'll see.
