The wonderful thing about all the services Google is creating is how clever people leverage them by adding content from disparate sources to create new services totally unimagined by Google or anyone else.
For example, imaging merging Google Maps with, say, real estate offerings on CraigsList. That way one could navigate by map, looking only at the interesting locations, instead of having to read every single ad to visually extract the particulars. Oh, and having the listings filtered by price, as well.
The result is impressive: it's a fast, easy, and convenient way to discover that one really can't afford to live in any desirable area, and even most of the undesirable ones, either.
The street finds its own uses for things.
