Location-Aware Social: Foursquare

Foursquare is a mobile application that combines the Social Impulse with the geo-location aware features of a mobile device.

Here's how Foursquare describes its features and benefits:

• Foursquare uses geo-location to offer users food and activity solutions "near them."
• It also uses geo-location to meet the social impulse: Foursquare lets you know if friends are nearby
• You and your friends can also 'rate and review' - we trust the opinions of those we know most
• Foursquare delivers value to users by passing through 'deals' from local businesses 
• Foursquare offers incentives to users to 'be social' through gaming features like awarding 'badges' and earning the title of 'Mayor' of frequently visited locations.
