If we want to make location based services successful, we can't expect users to stop and think "is that a sensitive location that I am tweeting about?" or "what are the implications of posting this status update on 4square?" every time they post a status update. That will just kill these services.

What people really need is a way to define exactly when, where and with who they want to share their info. They don't want to share their location with the world – they want to share their location with their friends, so why not allow users to create some meaningful privacy rules?

Locaccino for example, is a location-based social network ( apps.facebook.com/Locaccino) which gives users the ability to better express their privacy preferences, using a privacy platform from Zipano Technologies (http://www.zipno.com). As a result, our data shows that users of this app share twice as much.
