Here is an article I found with information on Foursquare the geo-location social media site.  This was an interesting article because I have never really thought of Foursquare as being a useful social media site;  my initial thoughts on Foursquare was it is a creepy way for people to see where I spend all my time.  The things I took from this article were the fact certain business will actually offer decent discounts to individuals and also users can leave “tips” on businesses that could potentially lead me to buy or not to buy from a certain location.  Definitely opened my eyes to some new features I was not aware of.
