 Social networking started small and has exploded into the all-encompassing beast that you see today. Major players you hear about every day include Facebook, Twitter, LinkedIn and Foursquare. The possibilities for sharing your location and activities are endless, and now Facebook wants a piece of it all! iPhone users can now check-in at locations world-wide using just the GPS on their phone, and Facebook's new location-based feature, Places. Similar to Foursquare and Gowalla, Places is used to show others where you are or where you've been. As with other location-based services, there are limitations such as cell coverage and whether or not the location is currently listed on Facebook as a destination for users. Users can easily add new locations or report inaccuracies through the application. When logged into your Facebook account, Places will show a "Check-In" button on the screen. Pressing this at any time posts your current location to your friends' news feeds, as well as logs your name and the time of the visit on the business's Recent Activity page. You can also tag other friends who are with you and view any other Facebook users there at the same time by choosing the "People Here Now" option on Places. One important thing to consider when tagging your friends is whether or not they want people to be aware of where they are or were. Be sure to ask before tagging, or run the risk of being "that" friend. Currently the coverage is only offered in the continental US, but the creators have promised to have coverage for other countries and mobile platforms available within a short period of time.
