So maybe some racist white people might rate any area with black or Hispanic people as unsafe. Hopefully, if the area is actually not bad, some non-racist black or Hispanic people will rate it as such. The positive and negative ratings should cancel each other out in such cases.<p>The areas that end up with negative ratings would have to be rated such by users of all ethnicities, which more or less rules out too strong a correlation with race here.<p>The only problem is if somehow only a single ethnic group, like white people, uses this.<p>So, basically, I don't think this is going to be an accurate source of information here. At the same time, if it were to actually get widespread usage, I don't think it would be as bad as some people are making it out to be.<p>Ultimately, though, why not use something like city-data? The site is ugly as sin but it has basically all the information you could ever want.
