But why do people let the world know where they are? Not using the
device is not enough, It has to be switched off to avoid tracking.
Mine is only switched on when I am willing to accept calls or need to
make a call. That only amounts to a small proportion of my waking
hours so it is more often off than on..



My phone OTOH is always on except when it has to be off, eg whilst driving
a train. I rarely make calls and even more rarely answer incoming calls.
When travelling by tube I often read usenet, as it's an offline thing,
whereas trying to read Facebook or anything web or forum based is difficult
with just seconds of wifi at every station stop.
