>> Art Galleries and Museums (Here's an extension of the 'tourism' concept. Show people around your town before they come.
Our only real limitation is our imaginations.
We have the ability to describe and share, in detail, any object that we can get our camera to focus on with anyone in the world. Do you have access to something rare and beautiful? Now you can enable anyone to get a good close look at it. (Maybe you should invest in security before geotagging it =] )
The archival idea is extremely wide and fairly deep. Apply it to local trees, leaves, flowers, fruit, architecture, musical instruments, weapons, ruins, food preparation, fire prevention, etc., etc.
It's the little things that you take for granted that you discover are completely different when you travel to another country or continent. We have the power to take anything we want about how we do things and broadcast it across country borders to deepen each other's understanding + broaden thinking.
