Yet another way for your friends and family to have up-to-date notifications of your “who, what, when, where and why” ? Facebook announced Wednesday a new location-sharing program that will allow you to send updates letting you announce your location. Similar to the iPhone application Foursquare that has been previously the leading location-sharing site. Foursquare reached a membership level of 2 million users in July.

Privacy uses have already been brought to the table with FaceBook “Places” as it gives friends the option to tag others when they check in somewhere, posting the updated location for everyone tagged. There is a “yes” option allowing friends to tag you, however there is not a “no” option, only a “not now”.

Facebook has said that “this is not a service to broadcast your location at all times, but rather one to share where you are, who you are with, when you want to…It lets you find friends that are nearby and help you discover nearby places”. The “Here Now” feature will let anyone who has checked into a pace see who else has done the same.
