Big news in social media is the app Color. The app, available on iPhone and Android platforms makes it possible to "simultaneously use multiple iPhones and Androids to capture photos, videos, and conversations into a group album. There's no attaching, uploading, or friending to do."
Sounds cool. My advice: run. The tech behind this tool is insidious.
We all know pretty much how GPS works. Geosynchronous satellites connect to mobile devices to pinpoint, within 50 feet your location. Color makes this possible by triangulating the position of individuals taking pictures of each other, or landmarks or just signage on a store front, send that information back to the Color servers... and tell exactly where you are even if you aren't participating.. even if you don't have a smart phone.
It's one thing to have voluntarily purchased a device that, when turned on, allows you to be found. It's another thing to have your location broadcast to the world when all you want to do is be left alone.
I don't tend to paranoia, but this is the first real commercial use of real Big Brother technology. This is not a good thing.
