I saw the same process with our Gmaps API coolaborative map in Mexico, when one same event is reported by multiple sources and starts duplication. I think this process is not an issue at all, think can be used to indicate some level of agreement between participants; that case of New York about highscool and Cancun that was repeated more then 10 times, can be represented as a level of consensus.
I think it is too early to put in practice validation procceses or measure the data accuracy, even on TV and governement sites the data is not homogeneus and there are contradictions. Im agree with Andrew Turner when saying dont discount the crowd, and let the crowd to be the validator of it self, like wikimapia is already do it (any one can describe a place with its tacit knowledge, and any one can vote about that description to dequalify it). There is another issue about the swine flu data showed in these maps, is not so clear whats the scale of the data or at which scale the markers were located? Country level, state, block, street level. How useful is to compair data expressed in a country scale, with an other located exactly over a hospital building? for example.
