Location services can be useful and fun, but, depending on how paranoid ("cautious") you are, you might already dislike the idea of a social-network dashboard keeping track of where you are at a given moment. After all, bad guys can use computers, too. Now, Foursquare may up your level of caution just a bit: CNET reports that "Beginning January 28, 2013, users' 'full names' will be displayed across the check-in service and venue owners will have increased access to users' check-in data, the company announced in an e-mail sent to users late last night." Users, though, "will still have control of the name displayed by altering their 'full name' in their settings," and can opt out of the increased flow of data to business owners. For users' sake, I hope Foursquare doesn't go in for the "real names" fetish to the extent that both Google and Facebook have.
