Ask HN: Is Geospatial MultiPolygon Data interesting to anyone?

So about a year ago a friend of mine and I succeeded in accumulating Geospatial MultiPolygon data for states, counties, cities, zipcodes, boroughs, and neighborhoods across the US. After getting the data loaded into a PostGIS enabled Postgres database we both got busy and kind of put our little pet project on the back burner.<p>We're currently revisiting the project and working on finishing up the API. Yesterday a thought occurred to us that we couldn't answer: Will this data be interesting or useful to anyone other than ourselves?<p>We would love to get the thoughts of the HN crowd figuring that if the data isn't interesting to anyone here it might not be interesting to anyone :)<p>You can see the data in action here:<p>http://geolayr.com<p>Thanks for the feedback!
