Thanks to Foursquare, Gowalla, Brightkite, Loopt and Yelp we can easily share our location with friends. Although many people gripe about how “pointless” it is to broadcast one’s location, I don’t anticipate the location craze ending any time soon. From Foursquare’s recent announcement about raising $20 million and now being valued at $95 million, it’s clear the company is doing something right.
