Location based services are very hot right now. Companies like Foursquare and Brightkite are taking location information and spinning it into the social web. Think Facebook or Twitter updates with geolocation information.

The creators of the Please Rob Me site simply say, hang on a second. If you are publishing this information publicly then you are also saying you are not home. The creators of the PleaseRobMe.com go into the why of the information was put together in such a convenient fashion here.

The site did get a lot of attention quickly and they've updated the home page with this post:
"We at Forthehack have been thinking about how we want to continue pleaserobme.com. It has received a lot of attention and it's time for a next step. We want to offer this website to a professional foundation, agency or company that focuses on raising awareness, helping people understand and provide answers to online privacy related issues."

Most services allow for you to set some sort of privacy controls. Know how to use those tools and know who is getting your updates.
