This "Boycott SOPA" Android app is absolutely brilliant!!!
It could herald the future of consumer political activism in an incredibly simple but very real way.
Here's how it works: scan an item's barcode, and it tells you if the manufacturer supports SOPA or not. You can then choose, right there at the store, to support them in turn by purchasing their product... or not.
SOPA is where it starts, but as the Extreme Tech article states, it could be developed and enhanced to be used for pretty much any cause you want; the possibilities and implications are endless. This is an absolutely amazing concept, and I can't wait to see what people do with it... Voting with your wallet could become the easiest (and most efficient) thing in the world.
