The maptimeDC.json file was made from a query to the twitter API with the string ‘maptimeDC’ on June 18th. So it’s a little old but you can kind of see what people were tweeting about leading up to their very successful first maptime gathering.
I just made a table from a couple of the parts of the data using a function I found from Shawn Allen in a JSfiddle example he made for someone. see: http://jsfiddle.net/7WQjr/
Now I want to think of more interesting ways to look into some Maptime Twitter data. If you want to see all up whats included in a tweet object or all the options regarding twitter queries check out their developer site and teach me how to make something cool!
