Yes, it’s that time once again, folks — time for the Friday Poll ! This week we want to get a sense of how Mashable readers are reacting to all the services and features coming online that allow us to share our location information, from Foursquare, Gowalla, and Loopt to geolocation features in services like Twitter and Google Buzz. With sites like Please Rob Me springing up to remind us all of the potential perils that might befall us as we start broadcasting our locations publicly and semi-publicly, it’s a good time to take stock of where Mashable readers fall on the spectrum

A new website called PleaseRobMe.com does nothing more than aggregate publicly shared check-ins, but its name and purpose attempt to shed more light on the dangerous side effects of location-sharing.

Foursquare is becoming synonymous with the concept of the check-in, but it hasn’t tackled location-based photo- and video-sharing — until now. Enter SquarePik , a new Foursquare app for the iPhone that adds photo and videos to the location equation.
