Too much of a good thing?

Not so long ago, it seemed so cool to share your location, but now social apps like location, check-in Foursquare appear like a quaint reminder of a time past. Recent news that Foursquare is to split its business in half, from the commercial to the social appears a bit like a last gasp at relanvancy, really not sure if it's the right move in the current climate. Post Snowden personal data is not something most people want to leave lying around. I was pondering such things when I came across these two pictures of the perils of location aware mobile devices being left in passive mode. Again, its not the tech at fault more the understanding of the power we weld even in passive mode.
