A few days ago I blogged about location-based services and their privacy risks and implications.

I was not that wrong, apparently, if you read this scary article about what happened to people on Foursquare.

Now I also understand why social networks like Facebook have not yet rolled out location-based features which could kill, in under two seconds, Foursquare, Gowalla & co.: it would be a boomerang for them, so don’t expect features like this to appear soon in the wild.
