Firstly, plazes will try to guess where the user are by identifying the network address. If it's not correct, users are able to update the guess.
To check in to a place, an user needs a program called Plazer which helps to:
- - List your online buddies where they are
- - Add new Plazes
- - Automatically check in at Plazes
- - Conveniently edit Plazes descriptions
- - Add your current location to applications like Skype, Google Earth, AIM and more.
Plazes also includes a service where users are able to mesh their Flickr pictures together with Plazes. Earn karma points when you discover a plaze to get in the top discoverer's list. Users are also allowed to build stuff on top of Plazes with the API provided. Build your own map, import it into a calendar and even show the current Plaze info in a blog.
Here's an example screenshot of plazes.
