The (now defunct) page http://stream.twitter.com/1/statuses/sample.json used to return a continuous and endless stream of JSON data.
I\'d like to process it using jQ
The url you have specified in your question sends a JSON response stream. Due to cross domain security restrictions in browsers you cannot access it using javascript. You will need to implement a bridge server side script on your server which you could poll at regular intervals using AJAX requests or host your site on twitter.com. The first seems more feasible.
