It’s like Foursquare and Facebook Places, but a little less voluntary. Making its debut at the IEEE International Conference on Distributed Computing Systems (ICDCS), eShadow is a smartphone app that will let you identify people in the neighboring area who are also using the same software. Then, it points you toward them.
While I am certain there are a lot of people who feel otherwise, I’m still not sold on the whole “checking in” to places thing, whether it be through Foursquare, Facebook, or Google. That said, the newest release of Google Maps for Android devices might actually help with some work-life balance issues.
