Cult of Mac has a great write-up of an app for iOS called Girls Around Me, which essentially displays check-ins and public profiles of girls around you. With a little shift in context it could easily be confused for a hot new startup (discoverability meets speed dating!), but no, it really is just a way for guys to creep on nearby girls who have failed to lock down their info.
It’s sad, but maybe something like this is what people need to shock them into understanding just how much information they put online.
The app itself is pretty much straight-up stalker material, but the fact is it uses publicly available information — information that, really, is being deliberately broadcast. There is a larger debate to be had about the nature of privacy and how information like location and profiles should be handled, and many subtle points to be made. But right now it seems that things must be done in broad strokes, and it’s only mainly broadly offensive things like this app that will bring attention to the issue.
