Just as an FYI in case Facebook users panic, here’s some info cut-and-pasted from Facebook Help pages:

 

What is Places?

Places is a Facebook feature that allows you to see where your friends are and share your location in the real world. When you use Places, you'll be able to see if any of your friends are currently checked in nearby and connect with them easily. You can check into nearby Places to tell your friends where you are, tag your friends in the Places you visit, and view comments your friends have made about the Places you visit. Use Places to experience connecting with people on Facebook in a completely new way.

Who can use the Places feature?

At this time, the Places application is available to users in the United States with mobile access to the Facebook application for iPhone or touch.facebook.com. Places will be rolled out more broadly and to other mobile devices and the web in the future. Please make sure that you are using the most up-to-date software version for your iPhone, Android, or mobile device or the Places application may not function properly. Alternatively, you can access the Places application through your device’s web browser

 

So, unless you are in the USA, there is currently no issue. And unless you actually choose to use the Places application, no geographical information about you is either captured or made available to anyone else with the except of the “Current location” text on your main profile page which you enter yourself manually.

 

Best regards,
