"Local" is getting more and more important with each and every development, such as this one.
Earlier this year, Microsoft invested 15 million dollars into Foursquare and the fruits of that investment are starting to pay off as the data is now being integrated into Cortana. The feature is now able to pull in data from Foursquare to help suggest local places that you might enjoy visiting. Microsoft Adds Foursquare Data To Cortana [neowin.net]
Because of Foursquare's massive database of user-centric data around local attractions and Cortana's knowledge of your habits and preferences, she can easily aggregate this information to give customized suggestions for places to eat or visit. It's a great use of both platforms and when they are combined, they are able to offer up smart recommendations that help to differentiate Cortana from other digital assistants.
