It is becoming too easy to pick on Google. There are many Web apps that use location. BestBuy, just to pick one arbitrary example, will ask permission to discover my location in order to show me my nearest stores. This is, of course, very useful, and I am happy this service exists. What I do not know is whether or not BestBuy or many other companies are sharing this information with other companies. My assumption is that BestBuy et. al are using a middleware web service, and that company probably makes money selling location information to advertisers.

For me it is just depressingly hopless: as soon as I go on the Internet of phone network, I have given up a lot of privacy.

I think we have a different definition of "very useful". I find it intrusive and routinely deny those requests. It's simple to pop my zip in a form to find the nearest store.
