Should there be a single site for all the world’s infrastructure problem reports?

I read about Fixables on Twitter. The site’s vision is pretty simple:

(1)  visitors find specific (infrastructure) problems exist in their town/city that can be fixed
(2)  they upload images of the problem to the site (graffiti, broken stoplights, furniture on the curb, trash, broken playground parts, broken apartment heater, skunk…) and mark the local on a Google Map along with some descriptive information
(3) the site notifies the “right” people
(4) the community puts pressure on to get it fixed

The tag: “Working together to fix our neighborhood, community, country, and world.”

There’s no “about” information, so its unclear who is behind it or if the geography to be covered is limited in any way. The map does default to California, however. Great concept; I’m just not sure it should be global. Locally we have 311, the phone number for government information and non-emergency services, which works pretty well.
