You might want to run that json through a prettifier.
It's definitely on the todo list and will definitely be done when I sit down to work on the map (thanks NYC for the PLUTO data!). I just load it up through python and it prints prettily enough for me, sorry for being lazy. Also, if anyone has any insight into the completeness of the data, please let me know (i.e. if your address isn't in the data but you are a happy(?) customer of Verizon FiOS). It is a skimpy list, but I'm used to low expectations being surprisingly disappointed so I'm not writing it off yet that it isn't complete.
