A wiki can work when it is used as a tool for collaboration by people who already share a common purpose and common philosophy, and when there is already a strong sense of community amongst the collaborators, and they already have experience in resolving disputes amicably, or at least efficently, among themselves. However, if these things are not already in place, adding a wiki will not make them appear, and in fact the wiki will actually make their absence more strongly felt.
I suspect that the GPS wiki escapes the problems of other wikis because by its very nature it cannot "atomized" the information. GPS addresses are discrete self contained packets of information. No one is going to be stepping on the first two digits of a posted address for a location. In a way it is as if WP editors had to submit complete articles in each edit. This weakens the market simulation aspect and helps avoid some of the worst dynamics.
