Plyce is the latest entrant into the location-based social network market. It is a market that is currently dominated by the likes of Foursquare, Brightkite and Gowalla.
Plyce uses Google Maps for many of its featured networking options. With Plyce you can find where your friends currently are and see which of your friends are around your current location directly from the in-built Google Map.
Plyce also lets you check for friends you have in common on Facebook with people around your location. So if someone in your immediate vicinity is friends with one of your friends they will show up on your map.
This one degree of separation feature could just be Plyce's unique selling point and certainly could prove to be a great networking tool.
Plyce also lets you check into and save your favourite places, gives you badges and has a weekly ranking table of users.
