Hey Mac OS X geeks ;) I just installed this launcher for the location-based service Plazes. I like Plazes since it's a very simple LBS in which you define where you are and it tells you what people are in the vicinity (and whether or not they are part of your social network). This mac os x launcher makes the process event simpler, you just have to login in the status bar of your operation system and then you have your Plazes Buddies around. The cool point is that you can directly set your iChat status with your location, it goes like this: Why do I blog this? As a researcher focused on location-based technologies I try to test various applications. This one is relevant and interesting, the cost of using it low and it works pretty well. I like this iterative construction of the location database (plazes I mean, not the launcher).
