Facebook is no stranger to privacy concerns and is causing issues where employees are given free access to computer facilities as we examined at a seminar we hosted recently.
NowFacebook Places allows you to share your location with others. As usual, there has been much discussion about whether this is good or bad, particularly as all facebook users are already automatically opted-in allowing their friends to tag them. Many users feel that it should be the other way around - perhaps the more sensible option would be for users of Facebook to be given the option to opt into the function, rather than have to try and figure out themselves how to opt out! Having said that, it looks like the Facebook team have worked very hard to get their privacy settings right.
