As someone who works in web mapping, I have to quibble with "The Google Maps of...". This is just an interactive map - it doesn't have features that particularly resemble Google Maps, particularly navigation.
A bit of work on the UI would make this a really fun and interesting tool - currently it seems to be intended for people who know a lot about the dataset already.
