Why do you Check-In "Off the Grid" on Foursquare?

8/28: Results to this survey have been published to TechCrunch (http://techcrunch.com/2010/08/28/foursquare-off-the-grid/) When you check-in to a location on Foursquare but uncheck the "Tell my friends" option, the service will check you in "off the grid," noting that you're somewhere but hiding the location. Ever checked-in "off the grid" yourself? Would appreciate five minutes of your time to complete this brief survey. All results are anonymous and results will be published on my blog at (http://elapsedtime.blogspot.com/). I will tweet when they're ready (follow me http://twitter.com/hunterwalk) - hopefully by August 7th. If you have any questions feel free to contact me: hunterwalk@gmail.com. Note - i'm doing this survey because of personal interest. Nothing to do w/ my day job.
