MG Siegler on Techcrunch mentioned the other day that the location-based software company Foursquare is airing their first commercial on cable TV channel Bravo.

Are we ready for that? While it is true Google has added that feature to their new product Buzz  and Maps, the question remains whether we really need to show and check where everyone is?

I added that function to my in-laws’ smartphone because they were always calling me asking directions to certain destinations while enroute to the place. Connecting them to Google’s Latitude was the logical step to them and me. I’m not so sure that same practicality applies with Foursquare, though. Just the fact that sites inciting crime are brave enough to capitalize on location based apps worry me a bit. This commercial marks just is just the beginning of that sort of thing.

I guess my hope is that everyone who uses these apps use discretion, common sense, and only share their location with their trusted friends

Common sense, unfortunately, is not all that common.
