Well, of course the answer is yes.
But I mean as a tool for giving community groups a voice? A group had citizens mark properties in New Orleans that they wished were being used better. But they didn't do it on Google Maps or using GPS.
They used name tag stickers. But, instead of saying My Name Is... the stickers said I Wish This Was...
The stickers are low-tech, easily accessible technique that has a totally different kind of impact and reach than online approaches. But in some parts of NOLA it might be considered vandalism, too. Tell us what you think.
