Yelp CEO Jeremy Stoppelman recently criticized Google for the way the search giant uses its reviews within Places.
Facebook's opened up its Places app to thousands of US retailers, offering Places users deals and bargains through the company's iPhone app and via touch.facebook.com.
The American Civil Liberties Union (ACLU) of Northern California is apparently not a big fan of Facebook's recently introduced geo-location app.
Facebook has launched a geo-location app that allows users to easily share their location with other members of the popular social networking site.
Twitter has added a location feature, allowing users to tag tweets with specific places.
