Facebook is making waves once again with the launch of its location-based service Facebook Places. Along with the requisite privacy concerns that accompanies every Facebook announcement these days (the service is enabled by default), the obvious 700-pound Gorilla in the room was always going to be the ever-popular Foursquare. Innovators and drivers of location-based Social networking entertainment and information, Foursquare can’t help but feel a little threatened by Facebook’s invasion of their territory. Many thought that Facebook’s announcement of the new service signaled the end of Foursquare’s reign over the market. However, some were of the opinion that Foursquare held enough clout in the location market that Facebook entering the fray would only drive more people to Foursquare. In that scenario, Facebook would be very successful in making more people aware that there was such a thing as location-based social networking, but wouldn’t be able to convince those people to only use Facebook’s Places platform.
