This isn't a formal proposal so much as presenting an idea. When i was booking a hotel recently for travel, a friend who knew the area advised me that it was a dangerous neighborhood. That allowed me to find a different hotel in a safer area and possibly save myself some unpleasantness. This kind of word-of-mouth knowledge is the kind of thing open projects can excel at providing. The problem, of course, is a metric for something as subjective as "dangerous neighborhood". It it dangerous at 12:00 or at 01:00? Is it unsafe to park a bike/car there?
Would some tagging system to indicate dangerous area be desirable, and how would it best be implemented? Cheers P
