Reason and usability of converting data into geojson format

Data portal_geojson

 But the focus has been desktop users, not addressing the shift towards web maps and people 
 using it in “non-conventional” ways. But my belief is cost to build the data is 
 returned when users actually start using it, so let’s look to ALL the users.
 
 
 Reason for geojson:
 
 Aaron: 
 it is plain text (not binary like shapefile
 json is a native format that is easily consumable by Javascript... which is more and more popular
 the spec is 2 pages long and easily understandable by anyone
 It was developed in the open, and not tied to any one company (unlike shapefile)
 it is self contained... not a cobbled together set of 4-6 files like "a shapefile" is
