Overview

The JSON tweets records come off the wire a bit more heavyweight than we’d like.

A sample JSON file, reformatted for clarity:

"id"                           : 1012519767,
"created_at"                   : "Wed Nov 19 07:16:58 +0000 2008",
// twitter_user_id
"favorited"                    : false,
"truncated"                    : false,
"in_reply_to_user_id"          : null,
"in_reply_to_status_id"        : null,
"text"                         : "[Our lander (RIP) had the best name. The next rover to Mars, @MarsScienceLab, needs a name. A contest for kids: http:\/\/is.gd\/85rQ  ]"
"source"                       : "web",
